How Mars Looked Like 4 Billion Years Ago
Four billion years ago, Mars was a completely different world. It had blue skies, fluffy clouds, and flowing water. Today, the planet is cold and dry with no signs of life. The transition from an ancient habitable world to a cold desert is depicted in a new video released by NASA's Conceptual Image Lab.

I've always wondered if we can find some ancient life if we dug on mars. Something similar to dinosaurs on earth, but billions of years ago.
An ancient Martian city from billions of years ago.
I do wonder if there was life and what went wrong to cause Mars to be what it is today.
I often think about it too when I read or watch news about our little red neighbour... but since we haven't found anything more than soil samples and some evidence of water I wouldn't hold my breath. If there was life, it was only bacterial.. Its weird how space works, and even if there was intelligent life somewhere out there, we wouldn't be able to reach it due to the extreme distance required to get there. Can you imagine if it was easy for extremely advanced civilizations to get to us?
