Every one of these beasts and deities would not only defeat the Hulk but any other Marvel hero or villain. This is a list of primordial generative and destructive forces.
Atlas was strength personified way before the Hulk was and he can hold up the heavens. No strength limit. No contest here.
Not only would Archangel Michael defeat the Hulk, but he would thwack the entire Marvel roster into the abyss.
Though Marduk gave Tiamat the business, before the epic clash, the Hulk would merely run around and play on Tiamat's body. The conflict would not resemble a battle. It would be more like a person staving off a germ or something.
Cthulu. Rrrrrghgherrrghghgh!!! Not really primordial, unless you consider the tremulous psyche of Mr. Lovecraft primeval, but quite fearsome, and impossible to defeat with pure physical force.
The Kraken: It would rise from the sea, entwine the Hulk in a tentacled mass, and drag him back into the brine to drown. No rage-enhanced strength could break him free. These ancient beasts embody powers that are way beyond measurable physical strength.
The Midgard Serpent: When the Midgard Serpent howled after biting his own tail, the reverberations would fling the Hulk to a distant galaxy.
Gaia: Would nurture and calm the Hulk instead of fighting him.
Medieval Dragon: Canonically invincible.
Actually, any number of canonically invincible entities would either triumph or at least fight to an eternal stalemate.
