I don't understand people like you. Do you really think hundreds and thousands of people on this and other forums just sport
ads for nothing or fall prey to a collective delusion? Besides the whole picture proof section delivers more than enough evidence. If you're too lazy or lack motivation try to obtain it by educating yourself on the subject and reflecting upon it. Then put the theory to the test by yourself and judge after a few weeks. Otherwise just leave it. But just asking, if not demanding evidence has always a foul taste to it since it seems to suggest intentional deception.
Edit:sry for the rude tone, but sometimes I just lose my temper if someone refuses to bring about a certain amount of self-sufficiency in terms of researching, thinking and acting consequently. Seriously: what do you expect to hear from us, which you can't already find by yourself on the various threads on this board?
