WHY DOES NASA HAVE TWO MILLION PHOTOS OF THE MOON THAT YOU CAN'T SEE?

Is NASA looking for alien space craft, probes or creatures on the Moon? That is what one of their hired scientist suggests they do. This begs the question of just what is NASA's hurry to build a manned base on the Moon. More importantly why does NASA have two million images of the Moon that they refuse to share with the public. Unbelievably they reportedly claim that only 'a handful' of these images have even been analyzed by humans eyes! Why won't NASA publish these photos online where the people who paid for them can see for themselves what's on the lunar surface?
