If we follow the genealogies that is roughly the time period we get.
My point in this discussion though centers around the six days of creation. Can God create everything in six 24 hour days?
Of this we do have very strong Biblical support that the days in Genesis 1 are 24 hour days.
If we follow the genealogies that is roughly the time period we get.
But I can not see that it has much to do with how old the earth is.
genesis 2
4 These are the generations of the heavens and of the earth when they were created, in the day that the LORD God made the earth and the heavens,
We can see here that the author used days as generations.
We also need to consider it was after God did all of the work and rested that he made Adam.
Most believers will say it was just rehashed but I believe Adam was a special creation and was not part of the creation of man on the sixth day but well after that.
I believe that Adams people were called the sons of God and the men created on the sixth day were referred to as the men, here is an explanation.
genesis 6:2
That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.
Some people say they have found the missing link between apes and man, others say they haven,t but could it be that there never was any missing link and that the change came when the sons of Adam married unto the daughters of men?
I may or may not be on the right path but it is something to look into and I do believe it.
