There's Egyptian hieroglyphics which could be telling us about space travel. There's all sorts of conspiracies behind them, one being that we're the aliens who landed here from 'Planet X'. I think the Summerian tablets touches on this too ( I could be wrong there)
I think you've been misinformed there. I'm pretty sure Ulloa's penalty hit the moon creating Tycho in the process.
Murray's penalty landed on planet Nibiru.
Neither penalty collided. Nasa have confirmed this.
