There have been many studies by archaeologists and scientists. These people say that if Noah would have built the Ark as God had requested in Genesis 6:15, the Ark would not have been big enough to house the number of animals that God had also requested.
They also question if the floods happened as they say there is no scientific evidence of a flood.
IMO: God can work miracles. God may have temporarily expanded the Ark to be able to hold the number of animals that Noah brought onboard. God could have also destroyed any evidence of floods. God could have done this as a test of our faith. With no evidence people wouldn’t believe there was an ark or a flood of the earth. However, if a person is a true believer, they are likely to believe there was an ark and a flood, but being a believer, I can say, “God performs miracles.” I am a believer.
If anyone is a recovering alcoholic or drug addict and has attended AA meetings or NA meetings and have gone through the 12 step program, you know that you have a higher power. Your higher power can be anything you choose that you decide to make spiritual, but not religious. You could even choose to make your dog as your higher power and many have.
