If Mars formed life, then life on Earth could have been seeded by life on Mars, making every life form on Earth descended from Martians.

There's a lot to do in space. I want to learn more about the greenhouse effect on Venus, about whether there was life on Mars, about the environment in which Earth and the Sun is immersed, the behavior of the Sun.

Perhaps we've never been visited by aliens because they have looked upon Earth and decided there's no sign of intelligent life.

Mars once was wet and fertile. It's now bone dry. Something bad happened on Mars. I want to know what happened on Mars so that we may prevent it from happening here on Earth.

Venus has a runaway greenhouse effect. I kind of want to know what happened there because we're twirling knobs here on Earth without knowing the consequences of it. Mars once had running water. It's bone dry today. Something bad happened there as well.

I've been a minimalist my whole life, even if you wouldn't know it from my office.
