"The Cosmos is all that is, or ever was, or ever will be."
Sagan is defining the word. If something exists, then it is part of the Cosmos. If something will exist, then that will be part of the Cosmos as well. If the Multi-verse theory is correct, then every possible multi-verse exists within the Cosmos [according to this definition]. That's not philosophy.
I think it's likely that autochemoreplication arose many times on earth in it's early history, but only 1 instance took off and lead to the proliferation we have seen since. Only 1 instance gave rise to the RNA-DNA dance. The others weren't as effective, and were out-competed.
Dumb chemicals just doing what their electronic bonding characteristics allow. That's all that's necessary for life to start, and the people who study this professionally know it.
*even if there were a step to large to be bridged by chemistry and physics as we curretnly understand them DOES NOT imply divine intervention. It simply means we haven't yet discovered the mechanisms involved. Every time we didn't know how something worked (rainbows, eclipses, conception), science has discovered how eventually. There is no current reason to think that life will be any different at all. And even so, divine intervention would not in any way undermine the entire rest of the history of life on earth. The more we learn about the Universe and its history, the more we find there is almost no room for the Christian god of the bible to operate.

I guess that's one way to view it. But can you see that just because we don't know the specific steps involved in abiogenesis as it happened on Earth doesn't imply that abiogensis is therefore impossible? Because these days, as I've mentioned nearly every time you bring this up, the problem is NOT that scientists have no idea how life started - the problem is that there are SEVERAL different ways it could have started, NONE of which involve divine intervention*.c_h said:Th fact that he said we don't know how life came to earth was what i wasn't expecting, but all that was done about the issue was basically hand waving about the issue and not address it head on, since the rest of the story is dependent on life and if life isn't here, then the rest of the story doesn't make any sense. Basically life to come from dumb chemicals is simply impossible and they know it, but won't allow that to be known, lest it destroy the whole story
