I say "I don't know" nothing more. I don't know the absolute truth and it is the same for you. So don't pretend knowing (you or others) or talk about it with certainity. Often when people talk me about big bang they talk about it as if it was THE BIG TRUTH. Some people here are really blinded by their faith and their ignorence of knowing. Why it is so hard to say the simple truth "I don't know"?

Fact is when you KNOW. When you know for sure the cause and the effect...
When you can reproduce it, observe it, experience it, repeat the experience...
Big Bang is not observable, experimentable, reproducible, no one can see it. No one KNOW the cause because etc...
It is so far from the word FACT.
