Abrader, sharpening stone, petroglyph, or natural??

[mw44]

What are your thoughts?? I've seen many hand held size abraders online but not many larger stones...maybe I'm just not looking in the right places though. Maybe I'm completely wrong but these grooves don't look like anything natural to me. It has different width and depth grooves.
I've had a few people mention that it looks similar to the Lynco Petroglyphs in a nearby county.


Greenbrier Co., West Virginia.
Approx 2.5 ft length. Approx 80 lbs.
I believe it's sandstone but I'm not 100% sure.
Found on a raised flat approx 100yds from constant water source along with many more artifacts.

I’d say natural. The 2 lines that cross at nearly 90 deg are interesting. Coincidence? Maybe…

I’d also lean toward saying “natural”

I don't know if it would add better context but I should probably mention that within a couple months I've found multiple lithic artifacts and a few mason jars full of debitage within 150 yds of this stone on the same raised flat. Maybe it's still a coincidence but it made me raise my eyebrows lol. I'll attach a pic of some of the artifacts...

You have some nice pieces there, but that doesn’t convince me of the other rock being an artifact. I found similar this spring. Lots of debitage, a scraper and a point. I also had a rock with lines. Mine were put there by a farm plow, back when they plowed every year.
5 rose bushes growing near a zucchini, doesn’t change it from squash to rose. Good luck, and again, a lot of nice pieces.👍🏼
