Now I think about it, this idea of a war between humans and Martians is absurd. It's like a war between humans and cows.

If Martians wanted to remove humans, they could have just dropped their poison gas from space. Why put themselves at risk?
And what coud they possibly want with Earth? Their understanding of chemistry is thousands of years more advanced than ours. And so it their phsyics, so energy cannot be a problem. They can convert the mass of their planet into any resource they want!
Should I ask what were they really doing? Or should I forget them and explore my new mind? Or do something else?
