If we are trying to detect man we should look around 98.4 degrees F. Since God appears to be the sum total of all that is, I would suggest that, with the discovery of the Zero Point Field, we look for him at about 5 degrees absolute, which is somewhere around minus 268 dgrees F.
When looking for higher powers, always study nature, and eventually you will learn more about its source/origin.
But if you want to look for the “God” that people misconcieved, look inside of their heads and their books. Surely you wont learn much, but it has been appealing to some.
