Ok now on to how you said that Thor lifted the entire serpent this is the actual issue numbers and what happened:
(Thor issue #272)- While in the court of Utgard - Loki challenged Thor to lift his cat off the ground, but was humbled when the cat managed to keep at least one foot on the ground at all times. Utgard-Loki then revealed his so-called cat was actually the Midgard Serpent in disguise. A cat is one of the forms that the Midgard Serpent could take.
(Thor issue #380)- Thor and the Midgard Serpent engaged in a battle, during which Thor broke the serpent's teeth when it tried to swallow him. Finally, the serpent launched itself at Thor for its death strike, but Thor came back at it, unleashing the unfettered might of Mjolnir. The energies unleashed slew the serpent, and at the same time left Thor's body broken and pretty much beat it to a pulp.
(Thor issue #487)- Thor faced the Midgard Serpent in battle, but was quickly swallowed up. Unable to break free from its belly, Thor found himself exposed to the venom of the serpent's breath, and began to drift unconscious.
(Thor issue #488)- Thor was saved from death by Beta Ray Bill, who tore a hole through the serpent's stomach to reach him. The two hammer-wielders were able to smash their way out of the serpent's belly by combining the power of their hammers, and the Midgard Serpent faded back into Hel.
Maybe I am wrong but after I read the comics... nowhere does it show Thor lifting the Midgard Serpent. Also you were wrong because the Midgard Serpent does not weigh as much as a planet. He can encircle the planet. Because supposedly he is the son of a giant that Loki hooked up with.
Ok so now I showed you more proof of how you are wrong and you have yet to show me anything that are facts... that I can actually see and not out of the 'savagerampage encyclopedia of wrong facts.'
