I have 2 close friends who believe we've never been to the moon. I've tried explaining to them why the flag moved, why there is no need to go back, etc, and it falls on deaf ears. This morning i saw this video by nasa [ http://ca.news.yahoo.com/see-earths-moon-evolved-nasa-videos-140012773.html ] and it motivated me to make my two friends understand once and fore all. Aside from what you can find on google, do you PF'ers have a few in your face facts or outright proof that I could tell these two? Thanks!
