I admire your curiosity, I believe you have gifted mind and intelligent brain brother. This is the reason I do not believe you came from big bang, because big bang is;

Big Bang
It theorizes that a large quantity of nothing decided to pack tightly together,—and then explode outward into hydrogen and helium. This gas is said to have flowed outward through frictionless space ("frictionless," so the outflowing gas cannot stop or slow down) to eventually form stars, galaxies, planets, and moons.

No intelligent person like you who are typing and replying by using decentralized blockchain Hive came from large quantity of nothing decided and then exploded. There is Someone who is intelligent and smart who created us all. Thank God brother. May God bless you
