Look at the starts at night. What is the possibility that same star your looking at, somebody else is looking at it from a "closer" view?

We have found planets around other stars, some of which might be inhabitable by life as we know it. However, since there are trillions of stars, and since we have only looked closely at a tiny number of them, there really is insufficient data to state the probablity. However, it is very high that there is life somewhere out there in all of those trillions of possibilities.

"Likely hood" means a crook who is likely; I suspect you mean "likelihood" which is similar to "probability." Stars don't "have planets in there orbit"; they have planets in orbit around them. "Look at the stars at night"; this suggests to me that this is YOUR homework, not mine. I don't understand the last sentence at all; even if I substitute the correct "you're" where you have written "your"; the first is a contraction of a verb, the second a possessive pronoun. All of this suggests you spend more time studying English composition before you tackle astronomy.
