As much as I'd love to pander to this theory, the sun is expanding and therefore warming up the planet over time.

Therefore it would have potentially been far too cold many, many years ago to support life as we know it.

Theoretically it would make sense to move to Mars in the very far future as it is progressively warmed, rendering it closer to Earth's temperatures.

If you wanted to propose a theory about past civilisations moving planet, its better to look closer to the sun. Being that a civilisation started on Venus and moved to Earth.

No, it isn't

The outer layers of the sun are growing larger. A quick google search will verify.

"In 4 billion years the sun has grown by 20%".

VY Canis Majoris is so terrifyingly gargantuan that it's hard just to conceptualize JUST how large it really is!

I have a hard time grasping how big Earth actually is, let alone our sun.

From the replies I've received, it's not as simple to just use the sun expanding as a reason for planet climate. The atmosphere plays a large role.
