It's difficult to discuss with people that don't have scientific background...
I agree. When someone has an ideology or a religion to defend, rationality stops
Absolutely good points. When people believe in science theory, especially theory that can't defend itself in the face of stringent analysis - like evolution theory - they have a religion going for themselves. The religion of evolution.

''Believe in science theory'' Why do you need to believe in it? You can study it and see it for yourself that is real unlike religion, no matter how much you study it you will never find evidence for the existence of gods.
And then all you have to do is look at some good science theory that is contradicted by other good science theory, to see that science theory is an unknown.

I have yet to see another scientific theory that contradicts evolution but if you know one tell us, enlighten us please.
First, the point was that science theory is not known to be factual, because there can almost always be theory that contradicts it. So, evolution theory is not known to be factual, either.
Regarding evolution theory, we don't need theory to contradict it to show that it is false. Reality contradicts it in the way that every so-called fact of evolution can have some other, more realistic explanation than evolution. Besides this, there are the things of nature that show that evolution is impossible.

Nothing is known to be factual 100% I don't really see your point here. Things in nature like what? I'm still waiting for the examples of spontaneous generation of complex life as you claim god did.
