Ever consider that God’s day bears no resemblance to a human day?
Your purpose and perspective is to discredit. Your lack of humility is your undoing.
Looking at "days of creation" I believe Genesis teaches a 24 hour day.
Millions of years do not have a day and a night (singular) and then a next day.
Moses also recalls that God created it all in 6 days...."For in six days the LORD made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy." - Ex. 20:11
I realize a thousand years is a day and a day a thousand years to God, but not so in creation. If you look at what was created on the "day", what was created the next "day" was necessary for what was created the "day" befores survival. If it was a kazillion years in the making, it would have never made it.
