[Granny Bear]

I know in such a big universe it seems unlikely that we're the only ones...

But I don't think any of us understand, me included, everything that goes into sustaining life.
I read once that if we were one degree closer to the sun the earth would be too hot to sustain life.
One degree further away, too cold.

Our Sun is a small star so I'd imagine most stars put off too much energy.
Most planets are made of gas or ice.

But then again we've got mars and earth in our solar system that look possible to sustain some form of life.

To me, that bolded statement is quite profound and complex.
