Good. Glad you understand that.
Now let's take the next baby step.
We have one planet where we have really done much exploration, and in that one sample we find life existing under just about every imaginable environment.
In addition, all of the data so far indicated that the laws of nature and the composition of matter is the same everywhere we look in the universe.
Finally, when we have look around the universe we find that the elements we see in life here and many of the things we associate with life here such as amino acids are common throughout the universe.
As we learn more and more it seems that the planet we live on is not all that unusual.
So, since we know that 100% of the planets we have explored in detail have life, is there some reason to think that life might not be as common elsewhere as here?
Anyone so limited that they can only spell a word one way is severely handicapped!
