The Beautiful Universe, Created or Big Bang?

Some state that only a God can create such a vast and expanding cosmos. But when you consider why would a God create such a massive, complex and expanding universe when scripture only talks about life on earth and a place called heaven. If this huge complex of energy, gases and objects in an ever expanding universe is heaven, then why is it so expansive, destructive and dangerous? There has not been enough human souls on earth in its entirety to fill this massive universe, so what is the point if it is heaven?

But the Big Bang theory does start to explain how and why.

Why is it so hard to accept the science we are learning every year from our space probes and telescopes and we still accept ancient text written during a period of great ignorance of the universe and the planet earth, after all they thought earth was the center of everything and the sun revolved around earth, which was flat. Give me a break. Open your mind to the evidence that abound around us.

Is this the work of a God or the Big Bang?

If God, where did he come from if he created all of this?
