Ok, I'm gonna give this ONE try, but I don't think I'll get very far. First, if you're going to make such an assertion, that 'most' scientists agree on life that is or was capable of visiting our planet, you're going to have to prove it.
In any event, I forget the exact formula, but here's how it works.
First, we need to ascertain the number of solar systems, at least in our galaxy. Not every star is a solar system, ok?
Then, out of those solar systems, we must guess at how many have "Class M planets" (I was a Star Trek geek and sort of still am). That is to say planets simply capable of sustaining life, IN ANY FORM.
THEN, out of those, we must guess at how many were able to produce "intelligent" life. Right there the number has been reduced drastically, even though class M planets are hard enough to find as it is.
THEN, of those planets on which life formed and it became intelligent, it had to exist in a time frame during which WE existed as intelligent life.
If one uses earth and humans as the rule or guide on which to base calculations, and the uses civilization's existence (time frame), the chances of us being visited by intelligent extraterrestrial life become astronomically small.
But, hey, if most scientists agree, then just hit me with some names and numbers. My own sources can work on the veracity of your claims.
