Despite looking at it closely, I don't see anything that appears different from a few lines on the surface.
And I like seeing genuine ancient rock art or cave drawings etc.
Also, this photo has nothing in it to indicate scale.
And there is nothing in the photo, by itself, showing context or placement on any larger piece or structure.
If you see a figure, with a boat and details, then post a matching image with those outlined. I do not see a human figure in this photo, and I am usually pretty good at seeing symbols.
I don't doubt that some artifacts of ancient or prehistory (for that area) civilization or man's graffiti or art could be found. Easter island's large monolithic statues seemed mysterious for many years.
But, I think if you feel you have indeed found something more than a rock that appears to you as something decorated or built by man, this photo is not convincing evidence of it.
I hope these comments help you see the issue as others might.
