A Quote For Atheist to consider :

[Tiberius]

Atheism: The belief that there was nothing and nothing happened to nothing and then nothing magically exploded for no reason, creating everything and then a bunch of everything magically rearranged itself for no reason what so ever into self replicating bits which then turned into dinosaurs.

Makes perfect since.

A few points of contention:

1) Atheism is the lack of belief (or disbelief) in gods. It has nothing to do with the Big Bang, "creation" of the universe, atoms rearranging, life emerging, or evolution of dinosaurs. There is no atheist dogma that we all have to believe this, and I can name a few atheists who don't believe all of this at all.

2) That said, I do believe the Big Bang is the best explanation of the facts, because simple observation will lead to it as the conclusion. We know the universe is expanding; we know it is expanding at an accelerated rate; and we know that if we reverse the clock 13.7 billion years, we can calculate the exact moment everything started to expand. Yes, I said it..."everything". Not nothing. The only "nothing" that ever was in the Big Bang was space and time. The Big Bang is the expansion (not "explosion") of space and time, which at the point of the Big Bang were great big cosmic nothings. There was no space, there was no time. There was only an infinitely small (and therefore spaceless), timeless point which contained all matter and energy.

3) Who said there was "no reason" for the Big Bang? I'm sure there is a very good reason why it happened; many think it was a quantum fluctuation; some religious people who accept the science call the reason "God", and I don't have any beef with them. As far as I am concerned, you can place God in as many aspect of the universe as you like, as long as you accept the validity of the science which attempts to explain things naturally. Pantheists I get along with very well, same with Deists. Theists who always attempt to force God into the picture, pushing out perfectly valid science as they go along, will always be frowned upon in my book.

4) There is nothing magical about particles rearranging; they do it all the time, and there are many many reasons why they do it. The laws of physics practically explain why it is that particles move, and they've been explaining why for hundreds and hundreds of years. There is no great big mystery to why particles move or cells self-replicate; the only real mystery is how everything got started (abiogenesis, etc).

5) ...and finally, to sum up evolution as "which then turned into dinosaurs" shows a complete lack of scientific understanding which I can't hope to correct here. Do yourself a favour, and instead of trying to win converts at atheist forums by posting quotes that will just get you laughed at, why not better spend your time trying to understand why we think the way we do; why we believe such things as the Big Bang, or evolution, or abiogenesis. Do some actual reading of your own; stop listening to what preachers tell you you should think, and start reading what science can demonstrate to be real. Science won't ever tell you "this is true, you must believe this"; it will show you the facts, and it will give you an explanation (or many) that attempt to explain those facts. You don't have to believe the explanation; that's up to you, but if it fits the observable facts, why (other than being motivated by religious intent) would you choose not to.
