Scientist get things wrong all the time.
God does not need to prove Himself. He is everywhere in the whole creation. Some people just harden their hearts and believe all sorts of nonsense because humans are evil. If they admitted there is God, then they would have to admit they are sinners and deserve God's wrath.
Admiting to God also means they have to worship God, but people worship themselves.
It's pointless writing to you about God, because you don't want to believe, but I'll write to you what you and others need to know.
God is Holy, without sin. Sin separates us from God, and because we sin, we deserve to be punished. But God in His mercy judges no one by their sins today. He sent His Son so whomever believes in Him should not perrish but have an everlasting life. But because God is just, His mercy will end one day, and He will punish every sinner that did not believe in the Gospel of Jesus Christ.
