Not even the scientists and physicists at NASA can say what you said with 100% certainty, so what makes you so sure? Already there have been multiple planets considered to be habitable by NASA, and this is only in one region. There are trillions of other unknown regions out there.
Of course, evolution and the derivation of the human-form is still a just a theory with many flaws in it, but to come out of nowhere and say that something is "stupid" based on your own opinion without any substantial evidence or proof makes your statement worthless.
