Hello people.
This is my first ever post on the forum I would just like to introduce myself.
I have an O'level in chemistry. Thats it. No PHD no years of exerience, nothing realy. Ive been reading a bit on this, tonight for the first time. And to me it makes perfect sense.......... Please read on.
I dont know about physics, I'm not even quite sure how an internal combustion engine works, but what I do know is that if you take a gas and cool it, it condenses, (becomes liquid, I think. There you go thats about the extent of my knowlege.)
This being the case......
If earth was created Billions of years ago, soley of gasses and stardust, with the aid of gravity, it would have eventually created a mass yes (the Earth) surrounded by gases (Y/N?).
We are told that the "universe" is expanding, along with our galaxy, therefore the Earth is moving away from the Sun right? Eventually these gases surronding the earth would have condensed, to create a liquid covering the entire Earth. (Y/N?) (basic laws of chemistry and physics).
If the continual movement of the Earth moving away from the Sun caused a reduction in gravity then the Earth Would expand causing rifts in the upper crust allowing the liquid to subside, and the land mass to reveal itself.

Please tell me if I am talking from my BUTT, but if this is not a reasonable hypothesis then it goes against the laws of chemistry and phisics in my understanding.
Please excuse my spelling and grammar. I'm having trouble editing the post. Thanks for listening.
