Well first of all, everything you know about the universe comes from NASA and you've never actually seen any of these planets or galaxies with your own eyes and yet you trust it completely. Also yes, the universe and everything in it is an artificial construction. Inanimate objects can't just magically create themselves. Houses don't build themselves. Cars don't build themselves. Paintings don't paint themselves. Books don't write themselves. Yet you believe a planet which is infinitely more complex than any of these things can some how magically form on its own. I'll take "what's the opposite of logic" for 500 Alex!
