Good day to you!
I want to make a few corrections in your reasoning about Christianity:
- The divine and human natures are fused in Jesus inseparably and incomprehensibly. He became man for our salvation, otherwise, if He was only a man or only a God, He could not atone for the sins of mankind. So, He ate and drink like a usual man.
- God did not seriously seek for Adam, this was "sarcasm" on His part, since the reason of Adam after the fall was so dark that he wanted to hide from the omniscient God in a bush.
- God is a Trinity, but not three as a number understood by us. There is a difference between the three entities and the three persons. God is one in essence, but has three hypostases.
