FWIW, God does give us proof of his existence in nature.
Romans 1:20 For since the creation of the world His invisible attributes are clearly seen...
As our scientific knowledge has increased the evidence of God's existence is more and more clear.
God the Father has revealed Himself in four ways: 1) through the Person of Jesus Christ, His only begotten Son, 2) through the indwelling Spirit, 3) through Scripture and 4) through Creation, both spiritual and physical.
But science will not recognize this because under "methodological naturalism" it excludes God on principle. This means it accepts that science cannot "measure" God and thus cannot say whether or not He exists; and then proceeds with the assumption that nature is knowable and predictable and therefore, whatever the explanation for a thing is, it will be natural, or material, or physical.
Likewise the "historical critical method" of reading Scripture excludes the power of God on principle.
But here I am addressing specific demands for proof of God. God does not honor such demands, e.g. the demand of the atheist on the forum that if God would give her a bag of M&M's she'd believe He exists.
Man is not measure of God.
