Q: Where wast thou when I laid the foundations of the earth?
declare, if thou hast understanding.
A: For the invisible things of him from the creation of the world are clearly seen,
being understood by the things that are made, .....so that they are without excuse:
Job 38:4/Romans 1:20
"The faint young sun paradox. According to stellar evolution theory, as the sun’s core transforms from hydrogen to helium by means of nuclear fusion, the mean molecular weight increases, which would compress the sun’s core increasing fusion rate. The upshot is that over several billion years, the sun ought to have brightened 40% since its formation and 25% since the appearance of life on earth. For the latter, this translates into a 16–18 ºC temperature increase on the earth. The current average temperature is 15 ºC, so the earth ought to have had a -2 ºC or so temperature when life appeared. See: Faulkner, D., The young faint Sun paradox and the age of the solar system. As of 2010, the faint young sun remains a problem."
