Planets go thru the same stages? my "theory"?

Question

i have absolutely NO evidence to support this, just what I know about planets in our solar system.

But what if… all the planets in our solar system "grow" & go thru the same stages. but right now they are different stages.

First, here’s a quick summary about the planets (i got these from www.kidsastronomy.com & put them in my own words):

-Mercury has a thin atmosphere, spins slowly, and a wrinkled surface.

-Venus is a hostile, hot planet with active volcanoes and venusquakes (which results in moutains and valleys). Very much like Earth but too hot for life, due to the atmosphere, a thick cloud which traps heat.

-Earth, we all know what Earth is like.

-Mars is most like Earth than other planets, because of mild temperature (compared to other planets) and has frozen water. Evidence shows that Mars once had rivers, lakes, an ocean, etc.

Answer 1

With all due respect, that's a load of complete twaddle.

Answer 2

Terrestrial planets will not become gaseous planets.  There's no known mechanism that would turn a hot solid body so close to a star into a cold gaseous one.  The evidence tells us that most of the planets have been the way they are now since they formed 4.5 billion years ago.

Answer 3

If you think of the energy a planet recieves from the sun as cumulative, its possible to imagine venus could already be what the earth will become eventually. But there's no reason I know of to believe that we will eventually become a gaseous giant like Jupitor is now or that Jupitor will ever become earth-like.

I think the biggest difference is our mass which allowd most the lighter particles to be swept up by the sun, while out past a certain distance, the gasses were swept up by Jupitor and saturn and so on.

Answer 4

yeah
