If what I'm reading is as it appears (I've not gone back enough pages to catch up), I feel the need to share this quote from Sam Harris book I'm currently reading.
Tell a devout Christian that his wife is cheating on him, or that frozen yogurt can make a man invisible, and he is likely to require as much evidence as anyone else, and to be persuaded only to the extent that you give it. Tell him that the book he keeps by his bed was written by an invisible deity who will punish him with fire for eternity if he fails to accept its every incredible claim about the universe, and he seems to require no evidence what so ever.
Im starting to firmly believe people of faith have to open themselves up on their own to be reasonable. That's what had to happen with me, I had to be willing to consider other possibilities than I otherwise had been before.
Abiogenesis is a really amazing theory, one that was tested in a way in the mid 1900s. I recently read about the experiment and it's very interesting.
For more on these experiments read here.
I really don't see why abiogenesis should be any less probable than the existence of God, I consider it more likely TBH because there is more evidence suggesting it's possible than there is of God.
