Yes i know of all those paradoxes, but your grammar and structure is so bad that i don't know what your point is.
I'm guessing that you want to know if other people believe it. well....simply put, i don't lol. It doesn't make sense and there is a simple explanation for it. Take the tortoise one for example. Get your friend, put him 100 feet in front of you, tell him to walk at slow speed while you run at a fast speed. It doesn't take a genius to figure out that you will eventually catch up to, and overtake your friend. (Applies to racing also =D)
