Everything in the USA is mixed up or misleading or confused.
There is a very serious and aggressive attack against religion in the USA, so that the schools and colleges all teach anti-religion doctrines especially the anti God version of Evolution, and so Atheism has become very widespread.
================================================
Of course there is evidence, as there is lots of proof of God.
1) The Big-Bang is a scientific proof of the Creation Day which thereby makes the Bible account and that religious claim as proven true, and it points to a Creator.
2) The reality of ghosts and spirits and Demons as witnessed throughout humanity is a proof of the real spirit world / spiritual life.
3) Bible prophesy so extraordinary that it could not be faked:
The United States and Britain in Prophecy
4) Our own conscience which convicts each individual.
5) The human ability to communicate with the Father God.
And there is much more.
