Acutally the burden of proof would be on you seeing as your the one calling us stupid for not believing in your THEORY.
Neither dark matter nor dark energy have been observed directly and it is not (yet) understood what exactly dark matter or dark energy is. This means that the Big Bang theory currently satisfactorily explains at most 4% of what is thought to make up the universe.
Another question, where did the exploding atom that made up our universe come from? What existed before the big bang?
I'm not questioning the inteligence of those who have researched and made contributions to this theory. I'm sure they have more knowledge in their pinky toe than I'll ever have. The issue I have is that it takes just as much faith to believe in your THEORY as it does mine. So please don't belittle me for my belief system when I dont do it to you.
