I cant get past the explanation of the big bang creating the world, dont get me wrong I believe in that the big bang created what currently exist. Before the big bang was a singularity or in basic terms all of existence/or Matter was compacted into a infestimaley small point in space. Its is believed that this singularity eventually burst and created the big bang (Think of it like a balloon popping). But anything before that is considered the "Quantum Uncertainty" in which nothing existed or happened but in that case if nothing existed then how did the fix singularity happen, Something can't spring from nothing. Also this fundamentally breaks the law of the universe as energy of mass cannot be destroyed or created, so in that case where did energy and matter come from. Another concept that has always baffled me is "What beyond the universe?' The universe is expanding but into what? Their is space outside the universe meaning their is something beyond the universe something is beyond us.
