I don't mean this to sound hostile, but Such As? Could you please tell me what you consider (for you) to be the 3 most convincing proofs? And have you ever read critical reviews of them? And by critical I don't mean creationist, I mean any scientific analysis (creationist or evolutionist) that double-checked the claims of the scientist who made the discovery. You do know that there is a long list of "famous" discoveries that were either disproven, an exaggeration, or had some other problems.
There are myriads of reliable observations that point towards the process of evolution -- no one of them or even three of them can constitute a "proof," but taken together they fairly compel the theory. That's been the state of affairs since Darwin published Origins -- if he hadn't published someone else would have because there were dozens of people thinking along the same lines. Check out Alfred Wallace, for example.
