When I have more time, I'll give you more info, but for now I'll offer you a small bit:
I've read some of the work of Dr. Michael Behe, a biochemist who is vehemently against the theory of evolution.
Naturally he faces a lot of criticism, including from other scientists, so please do not mention that as though it is news to me or as though it is a reason to simply dismiss him out of hand rather than to think critically about his works as you would any other scientist.
Perhaps Behe's most famous work is "Darwin's Black Box: The Biochemical Challenge To Evolution", a book first published in 1996 and again in 2006. I have not read the book in its entirety, but as I said, I'm familiar with his work, and I believe what he has to say is at the least very interesting and at most a significant challenge to the theory of evolution.
By the way, I'm merely presenting you with ONE scientist who disagrees with mainstream evolutionary theory. I do not plan to debate his credentials - or debate his book or ideas as though they are my own. It's just something I thought you might find interesting, burnsy.
