Evolution is a theory that has been searching for facts to back it up since day one. How many theories are there that started out with zero facts, zero data? If Darwin had named his theory Adaptation, which most of it actually is, there would be no shortage of facts then or now to back it up.
Predictions made about fossils that have not been dug up yet are testable and have been tested.
The theory of evolution predates understanding of DNA. DNA data backs the theory of evolution. Pedictions were made (e.g. related species like humans and chimps will share most of their genome), these predictions were tested and are true.
The apparent relation of similar species is also data and backs the theory of evolution.
The same thing with the pyramids. When a bunch of "experts' can't figure out how it was done, they have to come up with a mystical explaination to explain their inadequacies.
Think of it this way. Would you invest in a project of someone with a hisory of promoting sand to gold machines or perpetual motion?
