In this video clip, Mars is discussed about how it was changing through time. Back then, they thought Mars might be "dead" but now, we're discovering water and slight forms of life. This scientific breakthrough shows the limitations humans have. After many milleniums, we still have not gone much past our solar system. We've only disovered other galaxies and and other planets but we still don't know much about it. We still don't know much about our solar system either. And Mars is really close compared to other planets many light years away. We should just focus on out solar system first and then venture outward.

I agree with you, about how
I agree with you, about how we should concentrate on our own solar system because there is still so much we have to discover. I like the video because it shows how Mars has changed over time. I remember my science teacher from 8th grade told me that if Mars started to show another place where humans would be able to live, we would all have to move their because of all the problems happening in Earth. xD
