What if the earth was once one of Jupiter’s frozen moons and that lost its gravitational pull and ended up in the suns orbit and after millions of years the ice melted which turned into the oceans? The one huge ocean that covered the entire earth acted like a blanket and now that the earth was so close to the sun made the earths core hotter and hotter which caused the heat to melt the rock which escaped upwards to the surface and formed land.

well i think you might have something there, i think that maybe a comet struck the planetoid and knocked it out of orbit of Jupiter and sent it tumbling towards the sun and got caught in the the suns gravity well and then formed the orbit we have today, now as for the molten core I'm not certain but i the planet is rotating at 1 G and the very weight of the planet would have to contribute to the formation of that, because if the earth was to stop rotating all together the core would eventually cool down, also i read some were that Europa one of Jupiter's moon has a semi molten core so why couldn't another one have a molten core as well, and if that is the case your idea might not be that far of the mark.

Well, Let's assume that Jupier's moons were once a part of Jupiter. The make up of Jupiter would not be consistant with the Earth's composite, so its unlikley that the earth was a moon of Jupiter
If the earth was covered with a blanket of water, how could the sun heat it's core without burning off the water first?
The magma at our earth's core did rise to the surface and cooled, which formed land. It is the land that sheilds the hotter core from cooling. But it wasn't the sun that heated up the earth's core. Five billion years ago the Earth was formed by "trash" left over from the formation of our solar system. This material coalesced into a massive conglomeration that gradually evolved (largely as a result of gravitational forces) into the spherical body we know today. During its coalescent period, the newly formed planet was bombarded by metorites, comets, and other solid subplanetary objects. The immense amount of heat energy released by the high-velocity bombardment melted the entire planet, and it is still cooling off today. Denser materials like iron from the meteroites sank into the core of the Earth, while lighter silicates, other oxygen compounds, and water from comets rose near the surface.
The earth is divided into four main layers: the inner core, outer core, mantle, and crust. The core is composed mostly of iron and is so hot that the outer core is molten. The inner core is under such extreme pressure that it remains solid.
Ultimatley, everything may have once been a part of each other and the "big bang" theory states that a hug explosion caused everything to be spread across the universe. Its because of the sun's graitational pull that our planets are where they are... else they would simply float endlessly.

Highly unlikely.
First, how is it that the gravitational pull was lost at the right time to send earth on the correct course to end up where we are today? Why are we not out in space?
And if earth was set off in a correct course, why didn't it collide with Mars and where are all of the crater impacts that would have been made by the trip through the asteroid field?
It could work, but there are too many possibilities.

I disagree. I think it was the opposite. The earth was part of the debris as was Jupiter that was thrown out by the sun during its creation so were the rest of the planets. I believe their cores were hot and their surfaces cooled over 4 1/2 billion years. I mean all the surfaces cooled except Jupiter.

I have a question for you-- where did you come up with a hypothesis like that! it's genius in my opinion, but why don't you look for some evidence first. there is no way the sun can be so hot it cre8s land on earth. most of earth's land was created by underwater volcanoes and such. (2) I may be wrong, but in terms of the solar system, we're not too far from Jupiter, we would have to be as far away as pluto to be a frozen moon.

Impossible, earth was formed about the same time as jupiter and what you describe could only take place in a span of millions of years, besides theres the asteroid belt it would have had to pass through not to mention mars, besides if this happened where did our moon come from?

I still tend to believe in Earth was formed by the Universe explosion.
Although yours theory sounds fun, the chance is still relatively small when compare with the chance of formed by explosion.
The Earth was cooled down after the explosion and thus form the core of the earth now..

How could it just lose its gravitational pull? Jupiter would not be so fast to let one of its moons stray off. Crazy hypothesis is right!

Explain why in the hell did it loose its gravitational pull?

"Lost its gravitational pull".
That's like time losing its direction and going backwards for a bit.
