"Is there evidence of something beyond nature?"
Of course there is. There are numerous eyewitness accounts which all compliment each other, ....
Who were these "eye-witnesses"? We are told that some saw certain events, but we are also told that thousands saw Superman flying over Metropolis.
... there is the manifestation of God in the flesh, ...
That is an unsupported claim.
... who also did many miraculous things to prove he was God ...
Truly, the number and nature of miracles increase in proportion to the distance from the reports in time and space. Were I more powerful than a locomotive, could I move faster than a speeding bullet, and leap tall buildings in a single bound, that would not prove me to be God.
... and then there is nature itself.
A tree: Therefore, God. A madman or an imbecile might accept such an argument. How is nature evidence of God?
If there was no evidence of anything beyond nature, we wouldn't have nature.
Your argument is that if there were no unreality, there would be no reality. Do you know how that sounds to a sane person?
Or at the least we would have no life to wonder about it.
Another hairless assertion!
If the appearance of wonders prove God, then David Copperfield and Penn and Teller must certainly be divine, for I have been eyewitness to the wonders they have performed. If the tree be evidence of an omnipotent, omniscient, benevolent creator, then so are
Yersinia pestis and
Plasmodium falciparum. The benevolent deity to whom you attribute yon miraculous cure of cancer (ignoring the doctors and researchers who developed the therapy), is that not the same deity who sent it?
I fear that the warm fuzzy dream of narcotic religion has made you very uncritical in your intellect. You see only what pleasant delusion allows.
