I am absolutely certain, with the certainty of faith, that human beings have been around for only about 6,000 years. In addition to Sacred Scripture, which alone would be enough for me, there's plenty of evidence to prove this.
I must admit, however, that I am a bit perplexed by what Sacred Scripture means by a "day" before the sun and the moon were actually created.
more like 12-15,000 yrs at most, Ussher was wrong on his 4004BC timing of creation.does not figure in many events/people and also, does not allow enough time for replenishing hte earth post-Flood, etc.....suffice to day, though, no apes-humans and no billions of yrs to slowly create!
