Now Buz, how am I to know if that is a long list of misquotes or not? Just because a scientist uses the word "God" in an isolated sentence in no way means that they were atheists and converted to belief of some kind, much less Christianity.
I'm not going to accept any of them out of context; least of all the one from Stephen Hawking, who is well known to be an Atheist.
So, if you would like to pick a few of the quotes and provide the surrounding context from whatever document it was plucked from, we can discuss it.
