you said it yourself theory is based on the results obtained through observations and experiments which anyone can reproduce.

let's take observation first, how did he Darwin observe evolution, unless he had a time machine, recorded earth's history from day 1 using his time space craft, and while back in the future, played all his observations in his PC. But wait! may PC or TV na ba noon panahon ni Darwin?

and now the experiments, even if Charles Darwin experimented on one stage of the evolution say for instance a whale shapeshifts(pardon the term hehehe) into an elephant, in a given period of time. That still proves nothing about evolution of humans.
