I'm on a tractor, topdressing a football field with mortar sand as we speak, so I can't give you a line-by-line. To be honest, though, I wouldn't be inclined to do that anyway, because there's so, so much here.
It seems like you're trying to do too much to make this Bigger and Better, and it ends up just being A Lot. I've read it three times now, and as I follow it:
1.There are three Mayan artifacts. Sort of. They're like miscellaneous breakaway Mayans. But there are three of them.
2. If you read the words on them, you go crazy. If you don't understand the words, you just brutally kill yourself with improvised weapons. Body horror ensues. If you do understand the words, you go into a coma for a conveniently round amount of time, your brain grows a lot (but you don't die, and it still fits in your skull, which I don't understand), and you're super smart, and you Know Things. I don't remember every aspect of what the Doctor does, and I can't refer to the draft without closing this and losing it, but it was A Lot.
3. We've only found two of the artifacts, and the second one was worse than the first, so the third one is probably really bad.
4. Some part of the anomaly (the doctor? The being/God/thing that the doctor is channeling? Something else entirely?) can hijack the Foundation's servers and uses that opportunity For The Lolz. Amy Schumer indeed.
Archaeology/ancient ruins SCPs have never appealed to me much personally because I'm a dunce about that aspect of history, and once you're digging in the ground, you could tell me you found Trojan condoms in the ruins of the city of Troy and I would pretty much shrug at you, because that makes as much sense to me as anything, so it's possible that I'm not entirely the intended audience here.
But I do know Too Much when I see it, and I see it here. I would suggest slimming down your concepts and your descriptions of them. If there are three items, I would suggest describing them concisely and identifying what we know about what happens if you're exposed to them. That, I could see getting into.
If you're super committed to bringing the Amy Schumer God-fan into it, I don't have any real suggestions about how to make that better. But I can tell you with some degree of certainty that readers will be more tolerant of that if they get to it after reading a shorter article than you have right now. Reader exhaustion is real. Help them. Help the reader.
