If He was revealed, why did He wait so long to reveal Himself? Humans have been around for 100,000+ years.
According to scripture, God revealed himself in the beginning by creating.
In the beginning, God created the heavens and the earth. [Genesis 1:1, KJV.]
Then God revealed himself to humanity, by speaking.
And the LORD God commanded the man, saying, Of every tree of the garden thou mayest freely eat: [Genesis 2:16, KJV.]
God revealed himself to Adam, to Abel, to Enoch, to Noah, to Job, to Abraham, to Isaac, to Jacob, to Joseph.
And then revealed himself out of the midst of a flame, within a bush that was not consumed, to Moses :
I am that I am. [Exodus 3:14, KJV.]
In the nature of God, it is impossible to 'discover' God.
He reveals himself.
