This dating always drives me nuts....Only because I took my carving tools and engraved an old rock along a highway in Virginia in 1989. I used my initials and a 1789 date.

Saying someone finds it 100 years hence, it is absolutely impossible that they say it was done in 1989.

A reasonably sane Archeologist would also note that the 1789 rock was right beside the shoulder of a road from 1989, and conclude that it was rather dubious.

See, you shoulda written “1989, B.C.” on the rock. That would’ve blown their minds.

You’re just showing off your willful ignorance and stupidity, because there are a variety of means by which your inscription could be dated more closely to 1989 than 1789. The means for doing so widely range from studies of the algae growing on the rock and within the inscriptions to studies of differences in the radionucleotides in the different samples of the rock and associated microbial lifeforms.
