[@Dead Girl] Yes I do agree with the facts you stated and that mankind has the capability to go out into space with the interest in colonizing the moon and other planets if we do mange to actually get that far, but at the same time you have to take in the consideration of technological advances that the mankind makes just about everyday.

While a child may be born on the moon and have a different rate of growth and changes to their body, they could as far as go to the heights and means of making an artificial colony or station that negates the outside of the moons gravity and set it to what we are a accommodated with now, Earth's g force 1 g. It is a possibility that this could happen which would nullify their spiral of doom for a time, but the possibility of what you said of us not being able to return back because of what planet they were born on could happen as well. The reason why[b]:[/b] [u][i]The Human Mind and Body[/i][/u].

The reason why I bring up the human mind is because basically we still don't know how to unlock the ability to control it and what we use it for in our daily lives. Yes we have the control of our muscles, eyes, mouth, etc..., but that is only just the pinnacle of what were able to process and command ourselves to do. I believe that if we do discover the key to it, we will sky rocket into an advance way of living and see a colossal change in our technological advances. Though at the same time, humankind should tread carefully if there is ever a point that we get to this stage. The state of your emotions can play a big factor into what we do and how things get done.

As well if were to get involved with other intelligent life forms, I wouldn't put it past them just look out politics of today..... They speak for themselves. 

We can't come together and see the bigger picture[b]:[/b] We are one planet, Let's see what else is out there; if we could do this and have a general focus on that, it would make things better for ourselves and actually stop destroying the only livable place we have as a home. Then again, we could've sent those radio messages out to the wrong species that could've taken them as offense and hell-bent on finding away to us, we just don't know. 

The logic behind one habitable planet out of- 10,000,000 stars in the universe, yes this [u]could[/u] be a fact, but at the same time it [u]could[/u] be a false, because right now, we have no true evidence to prove that and are stuck with the written theories, and the night sky of space. I'm not say that is wrong or right, I'm not saying I'm wrong or right, I'm saying its a possibility until proven other wise.
