well it is not the same as Geologists or the secular humanist Roman Catholic.
I have read so much stuff from I think all who do or don't support a Gap it is mind boggling. the amounts of info on both sides I have read and am still going through.
in between classes at the Bible college, Sunday and Wednesday services, bible studies, and now I am getting ready for a weekly Addicts meeting. and on top of reading 30 plus books in the last year on a host of Biblical subject and theology, and the new heresy's out there.
here is a link so you can read some study's done on the antiquity of the Gap view in the early church and in Judaism. the link will start you into further links to different studies. I want to emphasize I do not agree with all that this site promotes as to a gap.
