Living organisms

[brewer]

living organisms have always existed. Single-celled organisms came to Earth in a meteorite from another planet. Time goes without beginning and end
do you agree

Disagree.

The potential windows for seeding are narrow, and the conditions at each window were different, while the likelihood that alien biology would be suitable for any of those windows is slim.  Time may go without beginning or end, but life on earth had a beginning, and it was local.

I'm always mystified by people who feel the need to invent exotic explanations for life (or who premise other things which are their apparent focus, on the same).  Mostly.....because we see that life can and does work right here on earth all day every day.  You don't need a meteor - just the stuff that's here.  The mere existence of life as it is demonstratively proves this.  In fact, if life did come here on a meteor - it would just mean that wherever that meteor came from must have been just like..well...here.

bold mine: Yep, happened in area code 402. No long distance charges apply.

I don't agree.  We don't know that life exists anywhere but here on Earth and the Earth has not always existed.  I suppose it's possible that organisms came here on a meteorite but that doesn't mean life has always existed.  I read about them finding algae on the outside of the ISS and germs can be frozen and live so I suppose there is enough evidence to say that it's possible but that's all we can say.  As far as time going without a beginning or ending, I think existence goes without a beginning or ending and time is something that exists, but I think that time is very much local and can vary.  From what I've read, in a black hole, time may be at a standstill.  Supposedly if you fell into a black hole you could watch the entire future of the universe from your perspective inside the hole.  I think Einstein demonstrated that time is relative to the observer and to velocity.  I think that photons travel at the speed of light and so time for them is at a standstill.  

I think life came about by plain old natural causality here on Earth and that since it was a causal process it wasn't random or chance. It seems to me like the whole life coming here on asteroids is an extra unneeded step.   I hope that there are other life forms out there but I don't have any evidence of it.  I think that time is fascinating and we still have a lot to learn about it.

Given the bewildering variety of forms that life takes, it’s seems pretty clear that if a bunch of chemical come together under certain conditions, living organisms happen.

My understanding is that "life" on earth (self replicating proto-biotic molecules) likely started some 4 billion years ago in the proximity of hydrothermal vents, where proton gradients, heat from the earth's molten core as well as a plethora of weird and wonderful spouting chemicals comprised the "primordial soup." The oldest fossilised microorganisms yet discovered were also recovered from hydrothermal vent precipitate. Oh yeah, and I'm English - that's the really important bit

Why "organisms"? What about "alive"? What does it mean to be "alive"?

I commissioned this painting as an X-mas prezzie for myself

English is what you get when Vikings learn Latin and use it to shout at Germans.

I'm descended from Vikings and I'm currently learning Latin in University. Now I have to avoid shouting at Germans, lest I accidentally invent English twice.
