There are many hypotheses. But no one knows the truth. We're counting on religion in this.
I'm a Muslim. I think death is crossing into another world. After death, there is a new life. Either in Paradise or fire. Your work in life that determines
Your new life. For me this is the truth. But I respect the opinions of the others a lot.
I agree with you, I believe there are so many hypotheses that all of them are actually valid in their own way. I respect your opinion as well, after all, like you said no one knows the truth.
We don't know the truth. But something nice to look for the truth, even if we don't get to the truth. The important thing is not to stop discovering this life.
