So why is the big bang taught as fact when nobody was there to see it happen or record it. Also where did the big bang come from? Nothing can't create something. Also idk when the last time an explosion created something. Hoping someone has the answers to these questions.

uh..its the big bang theory...idk how you get theory and fact mixed up. and its origins aren't yet definable by current scientific knowledge thats why its still a theory. current theory states the bang was from a super dense piece of matter which created everything today, and not that something came from nothing. given we can't explain how the matter came to be in the first place though. we are limited by current scientific data but its still a very convincing case thus far.

It is something we will never know, no mather how advanced we will get over the years.

Basicly i like to compare it with the following:
Lets assume there is a god(s), then who created him (them) in the first place?

They can research all they want, but such things will remain mostly unanswered.

correct me anyone if i am wrong. but isnt it the white novas or whatever when a star explodes that created the elements of our Periodic table, ex: calcium came from some kind of star explosion.

Not quite sure where I said it was fact. But all of science classes in public schools teach it as fact. My question is why is it taught in public schools if it is just a theory and why isn't intelligent design taught in public schools either. Both are theories that cannot be proven through today's science.

because even though its a theory there is a lot of evidence for it just not enough to make it into a fact yet. whereas intelligent design has no proof and is just opinion.

So we have two theories but one is being taught as fact while the other is just considered an opinion? And I am not too familiar with the "lots of evidence" for the big bang. Please inform me.

such as our universe is still expanding which has been proven. there are tons of scientific proofs out there based on this theory that help prove the theory as a whole. you need to get educate yourself on the subject i'm not going to try and lecture this because then you take it as my opinion.

You are correct the universe is spreading outward. Why is it that after the big bang only one planet could have life on it? If evolution took place and the first cells adapted to their environment then they should have adapted on other planets as well forming different creatures that could survive in different terrain and conditions.

there is absolutely nothing that has any real proof in saying that life isn't all over the place in the universe. the odds are pretty good that there are other forms of life just because of the sheer vastness and diversity of what we've found so far.
