I'm totally on your side of the overall argument here, as I believe everything re: space/moon missions is aa fraud. I'm basically a flat-earther, so I'm in no way replying to defend science. However, when I fire a gun, what's forcing my hand backward (kickback)? Is it the bullet pushing off the air? No. It's the explosion occurring in a confined space pushing the bullet forward and the gun (and my hand) backward. I have no known experience operating in a vacuum, and don't even necessary believe a vacuum even EXISTS in "space," so I'm not speaking with great authority, but if one was floating in a vacuum, wouldn't something as simple as throwing a football in one direction have the effect of propelling you in the opposite direction to some proportionally corresponding degree? That what "the BIG guy" tells me, anyway. Kek.
