Ten Tails
To debunk two of those arrows in the scan, you can clearly see the arrows pointing to the "split earth" clearly is water as it's reflecting the visual of the explosions! That's not a split in the earth and the arrows pointing to the "oceans" is the ground that's apart of the mountain range as it looks the same. But I'll ignore that and address the said "feats" as if it was what you are claiming it is...
1. There is no evidence he split open the
entire planet itself, just a portion of what we saw and what we see isn't enough for planet level, heck splitting the planet in half would range depending on the timeframe and other factors so this is not supporting evidence.
2. Drinking the oceans was done over time, it's not like he sucked up all the planets water in a second given we've seen it's size but even if it did, you'd need a calc (I think one was made before) but you can't just say it's better scaling for planet level/supporting evidence without a explaining why something like that would reach such a level.
3. It hoisting up mountains (causing those massive explosions everywhere) isn't planet level... just eyeballing it and you'd get into tier 6 range given other factors. You wouldn't get planet level from these explosions and just saying it's enough evidence for planet level isn't enough.
Hagoromo/Obito and the DNA Sword
1. Hagoromo did not literally "create the world" (or whatever phrase people want to use to suggest planet level) with that sword. This is easily debunked by the lore itself when you just take a second to remember that Kaguya arrived on the planet before Hagoromo was born! How can he create something that already existed? There were even people there given Boruto shows use Ishiki (Kaguya's partner), latched on to a monk with Karma after Kaguya took his lower half and left him for dead which took place before Hagoromo and his brother fought Kaguya and thus before the sword came into existence. At absolute best, Hagoromo used the sword to shape the planet's surface as that's the only possible explination that fits "creating the world" or "shaping the land" or whatever and that would be considered creation and potentially around High 6-A I believe (which can scale to AP)
2. Obito's statement has been discussed extensively. Going off the destruction route which we already do as written on his profile (
Obito Uchiha) it's High 6-A (as calced on our
References for Common Feats page) because that's basically the minimum power needed to destroy the planet, you'd need an actual feat of him doing it to get a higher value.
Basically nothing in the OP definitively supports planet level or gives these characters planet level outright with the exception of Obito's statement and that has been discussed on multiple occasions and High 6-A was the end result. If you have no evidence i will close this thread.
