How did the universe come to be?
If your say a singularity, then I will ask what did the singularity exist in? For example you exist in Washington, which exists in the United States, which exists in North Anerica, which exists on earth, which exists in the solar system, which exists in the milky way galaxy, which exists in the universe,,, so everything exists in something.
Then I will ask where did all the energy and matter that made/makes up everything come from? Did matter and energy always exist or did all matter and energy come into existence in a zeptosecond^1000 after the big bang?(keep in mind neither can be created or destroyed).
Then my next question will be what happened that started the big bang expantion?(was it energy that existed before or did the big bang create energy?)
Give me your thoughts. Not parroted hypothesis.
