and what is the age of the earth?!, it is written in the beginning of this eternity God made all the universal creation in six days(144 hours), and then the first humans sinned and fell from grace, and thus "sin" and "death" began to reign in the world, adam was 130 years old when he begat his son seth, and then seth was 105 years old when he begat his son enos, and then enos was 90 years old when he begat his son cainan, and so there were 75 generations from adam to Jesus as it is written in Luke 3:23-38, which makes no more than 5-6 millennia since the beginning of this eternity, so the earth is no more than 5-6 millennia old, and the fact that some scientists found and claim(ed) the world is millions/billions of years old doesn't mean that it is really so, because there have been many angels of satan, even an entire kingdom of satan, that could perform/show many signs and wonders including materializations such as: aging of matter, materializations of fossils and remains of prehistoric manlike beings/anthropoids, animals and plants, materialization of prehistoric earth layers in the ground, etc.
Matthew 24:23-25 "if any man shall say unto you, Lo, here is Christ, or there; believe it not. For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect. Behold, I have told you before."
you speak of "eternity" as if you are blind or have no brain to reason, how is it possible that the time's infinity began or God started to exist just about 5-6 millennia ago without there having been anything before that?!, you just ignore many important things/facts/circumstances
