No you did, and I did read it, but since they have no empirically verifiable control for their radiometric dating system I do not feel any obligation to accept its results.
Or do you just think that the radioactive decay of a given long lived nucleus doesn't follow the same sort of rule as a short lived nucleus? This would lead you to accept carbon dating, but not uranium dating.
An alternative method for dating rock is using plate tectonics and the measurable rate at which continents are drifting apart... of course, assuming they've been drifting at a constant pace (will you claim that they drifted much much faster at the start so to make it seem as if they took millions of years to drift at a constant velocity?).
Plate tectonics also helps to account for the finding of similar fossils in continents now separated by oceans... and they have all been radiometrically dated in such a way that is consistent with constant tectonic drift.

First off, the moon... where did you hear such ludicrous number?
Here's a more credible source:http://scienceline.ucsb.edu/getkey.php?key=373
The moon was indeed touching the Earth about 4 billion years ago. In fact, Earth and Moon were formed from a collision of a Mars-size planet (proto-Moon) and a Venus-size planet (proto-Earth).
No, I am sorry that just doesn’t work out.
1. Due to tidal friction slowing the Earth’s rotation, the Moon is receding away from the Earth at a rate of nearly 4 cm a year (according to NASA). Due to angular momentum this rate recession has been decelerating meaning the Moon’s recession would have been far greater in the past. Even if this rate were constant the Moon would have been touching the Earth 1.37 billion years ago, not 4 billion years ago. The laws of physics makes this problem very clear cut.
But your model does not account for ice ages, where all the water is locked and that mechanism doesn't exist, thus bringing the moon a bit closer.
Now, how many ice ages has the planet seen? How often?
But radiometric methods yield the same age for the moon and Earth. Consistency is good.
(May 22, 2013 at 8:03 pm)Statler Waldorf Wrote: 2. The Giant Impact hypothesis has some rather fatal flaws, including the fact that the Moon’s iron content is not consistent with being created by an impact, the mass of the impacting object required is far too great (the resulting debris must escape the Earth’s Roche Limit in order to to coalesce and form the Moon), the absence of rings formed by the debris that landed within the Roche Limit, and the absence of any magma lake created by the impact.The link I gave you provided a collision of a mars sized rock with a venus sized one... That's looks pretty large. And don't forget, at this time, these rocks are still quite hot and malleable... think Earth's core, lava.
The debris must not have gone that far out and was attracted to both resulting bodies.

How? Knowing the rate at which the fusion reaction occurs, calculating that, at the start you have the whole sun composed of hydrogen nuclei, use some mass spectroscopy to figure out how much of hydrogen and helium you have in the sun now and bam.... an age of about 5 billion years comes out... Now if only we could repeat this for other stars?... well we can? please do it! Ah, but it's only valid for stars close enough, because other galaxies are moving away, and we get some red shift and we'd also need to account for the time that their light took to reach us... well, astrophysicists haven't been idle, so they gave us those numbers and place the oldest visible stars at some 13~14 billion years old. Rendering our sun a second generation star, which it would have to be, if it was to have rocky planets around it. This means that the star that blew up and provided our sun with it's fuel lasted for less than 8 billion years...
So many assumptions my friend; however, that’s not what I meant by empirically verifiable controls, what I meant was accurately dating rocks of empirically known age. Empirical Science requires direct observation and repeatability. You have none with radiometric dating, it’s all extrapolation based off of assumptions.
QM tells us the rate of fusion reactions.
Mass spectrometry tells us how much of each element the Sun has.
Plug one into the other and voilá. I don't see assumptions.
For rock datings... yeah.. I already mentioned plate tectonics.
And radioactive decay is quite accurate.... also coming from QM.

Not all species were created at the same time, but all of the major kinds of animals were. But yes Humans and Dinosaurs would have coexisted, I see no issue with that, there are numerous animals we coexist with today that are dangerous to Humans (Grizzlies).
Look at the evolutionary idea: apes evolve in the safety of trees, as it becomes safer to walk the land, they descend and get nimble at walking up straight, because, at that particular geographic location, there are very few, if any, predators.

I think you overestimate how dangerous Dinosaurs would have been, many scientists today question whether T-Rex (who was most likely a scavenger) could have even run because of his body proportions, there’s a reason they went extinct.

Well when Humans appear with an extra chromosome it seriously jacks the system all up, I am not aware of any observed cases where it doesn’t make the organism incredibly unfit for survival.

Are you seriously considering this?
10 generations and you could get 50% degeneration..... 20 generations and total chaos... Tell me, do you accept that humans existed 20 generation ago?... That's about (1 generation every 30 years [high estimate, I know]) ~600 years ago!
No that’s not quite how the percentages work; Humans have been around for fewer than 250 generations which is fine given the rates of genetic entropy, it’s doubtful they’d last another 250 generations though.
The 3-5% rate is taken from the following study though…
Crow’s “The high spontaneous mutation rate: Is it a health risk?” published in the Proceedings of the National Academy of Sciences number 94
Didn't read the whole thing, but I did read some particular bits:
- mutations arise primarily from the father zygote, given that the father produces millions of sperm per day, the odds of some error are greater than on the mother's side, who produced all the zygotes before birth... this checks out with something I read recently that stated that there are more autistic kids from older fathers than from younger ones. IF you're over 35, you have a higher tendency to produce an autistic child than if you're 20.
- Deleterious mutations are removed from the population in about 80 generations.
- On the other hand, there's this gem "In [...] people, recessive mutations may persist for thousands of generations. "
Thousands of generations.... and yet you claimed that "Humans have been around for fewer than 250 generations "... Another piece of your story that doesn't add up. Care to produce some evidence for this 250 number?
Or should I just take your word for it?

Which hypothesis is correct... we'll see when we see. Until then, the best course of action is not assume anything.
Concerning the evolution of dinosaurs int o birds... it took quite a lot of time for that to happen and it is based on feather-like imprints found in some fossils, so there's some reason to that.
Turning helium into other (heavier) elements is something known as Nuclear Fusion, which opposes nuclear fission, whereby the nucleus would be torn apart resulting in lighter elements.
I believe you've heard of nuclear power plants, no?... they operate on the fission principle.
You've heard of Little Boy? That one used fusion, of hydrogen into helium... that's why it was called a hydrogen bomb.
Nuclear fusion and fission are real processes that affect our daily lives, one way or another. They are not myths.
