I have been Goggling " how long were Adam and Eve in the garden"and I truly believe NO one has a clue how long they were in the garden before being driven out. There is NOT any scripture that says anything about how long they were there.
It's not something you can just Google, as there's no real evidence for it, only circumstancial pieces of a puzzle.
The first is that, as KR implied, Adam and eve did not have sex until after the Fall. Second is that Adam only lived to be 929 years old, which would throw out the "thousands of years" theory.
Third, Eve was created perfect, meaning her menstrual cycle would have started the day she was created, aka Day 6, with no issues at all throughout. Extrapolate that out, and the earliest she could have had conceived would be very early on indeed, less than a month.
Fourth, throughout the Bible, the number 13 has signified rebellion and lawlessness.
Fifth, still pertaining to the number 13, is that it has remained ingrained in humanity's memory that 13 signifies something bad.
There's more to it than that, but it's all I can remember off the top of my head at the moment from the Bible Study.
True ,and you made good points.
I have read from those who believe they did not last a week to those that believe it may have been thousands of years before the fall, and NEITHER has any scripture to back up their position.
Same with marital relations as to when scripture is silent.
So in both I don't know !
