Imagine if you will our solar system as a binary star system many billions of years ago. The outer planets warmed and illuminated by our second sun. Life was a part of mars that existed and thrived as a result of the warmth of the suns and the abundance of water.The star being much older than our young sun entered it's final stages of life one day and the poles of the star happened to perfectly align with the planet mars and mars suddenly takes a direct hit from a polaron burst which completely annailates mars the intense gamma radiation vaporizes mars beautiful oceans it releases cosmic lightening which also hits the planet (the scarring on mars) this by the way matches the Thunderbolts theory of the electric universe. What life managed to survive on the planet dies out due to radiation poisoning, starvation and thirst. The massive amount of heat from the gamma radiation quickly weakens the magnetic poles of mars and the poles slip and we are left with the planet as we know it today. Total devastation. No one race of beings has the power to do the things to a planet that was done to mars not even with nuclear weapons. A cosmic scale event is what we are looking at. When the star finally exploded the leftovers of dust and gas drifted and the gasses were absorbed by our gas giants, and the sun. The astoroid belt absorbed the solid chunks of rock and any dust that was not trapped in the gas giants rings. What we have left is our system today.
