Not much. I focus more on things relevant to me and my life... seriously, how much have you read about other ancient religions and their evolution ??..
.. for instance, are you familiar with the ancient Sumerian trinity where the Babylonian triad consisted of three gods of equal rank? In ancient Egypt, Amun was three gods in one ..
.. I do not mean to shake your faith but there are numerous correlations between ancient religions and Christianity. Why not study them to increase your understanding of God? Why limit your spiritual growth? Does knowledge frighten you ??..
Yes, I'm familiar with both of those.
Correlation? Hardly. Comparing the Babylonian religions to Christianity based on apparent correlations is like saying Libya is just like America because they're both a nation.
