The whole, basic idea of Christianity and the Bible is this.
God is infinitely stronger and more intelligent than people.
People all over the world turned against God to their own hurt.
God offers a way out of their impending destruction ... through Jesus salvation.
Some people accept Jesus salvation.
Accepting Jesus salvation doesn't make anybody righteous in the way he lives this life.
Jesus salvation saves people for the New Universe God is making.
There will be no imperfection in the New Universe.
Think about this. There are only a small handful of people in recent years who have claimed to be over 120 years old. There are only about 3 or 4 who have claimed to have reached 200. People die. People need salvation from death. God is way stronger than people. He has offered Jesus salvation, the only way
Forget the wrong things that people do. Aim for the thing that is important. Jesus salvation.
Let me stop you right there (bolded sentence): God does not exist.
Your religion of atheism goes against the proof:

Perhaps if you could come up with a way to rebut the info found in the links, what you say might have some strength. To simply say it, doesn't make it so. Saying it without proof makes what you say a religion.
An honest answer to your question: "What created big bang, or what was there before the big bang?" is "I don't know", not "God did it".
Same goes for the question: "How the universe will end?", is "I don't know". Although top theoretical physicists have suggested few possible outcomes.
You are just making bunch of assumptions and conjectures instead of just to say: "I have no idea how the world was created.".
It is ok to not know stuff.
BTW, you have no idea what a scientific proof entails.
