Puleeeezzszeee! Just because someone used that flawed logic to establish the scriptural age of the earth doesn't validate it or it's assumptions.
Good grief man. Thats not what scholars used to determine the number of years since Adam. Its common knowledge that the work has been done on genecology and the age of each of those listed. Extensive study has been done and pretty much settled on the number of years it has been since Adam. Thats not in dispute but for maybe 50 years where there may or may not be some differences. In your zeal to be right your beginning to look a little lax on facts and study.
Im beginning to doubt that you do much extensive study of scripture whatsoever.
