“To our knowledge, life exists on only one planet, Earth. If something bad happens, it's gone. I think we should establish life on another planet--Mars in particular--but we're not making very good progress. SpaceX is intended to make that happen.”
— Elon Musk
Simplified Meaning:
Life, as far as we know, only exists on Earth. If something catastrophic happens here, all life could be wiped out. Therefore, it's smart to think about living on another planet, like Mars, as insurance. This idea is like backing up important files on your computer. If your computer crashes, you won’t lose everything because you have another copy. Right now, we aren’t moving fast enough to achieve this. SpaceX, a company, aims to solve this problem by working on technology to help humans live on Mars.
