I dont blame them either. Take the battle of l.a. for example. This is one case where there are supposedly tons of witnesses, photographs (1 good one), the military is involved etc.
Now this all sounds fine, sounds like we have a good presentation. But when you try to back it all up, its pretty hard.

But, maybe off-topic, but just out of curiousity. What made you change your, as you said, mindset into a more tolerant approach?
I agree. I don't think it's really worthwhile trying to convince anyone. Regardless of what evidence you present, at the end of the day, the person you're trying to convince has to have the openmindedness an willingness to at least accept whatever informaton you're trying to convey as at least possible.
In other words with at least the faintest belief in a possibility of extraterrestrial life, any try to convince a person is absolutely futile.

And further we may both have to apologize to Dulcimer since this could be headed way off topic.
Question: On what percentage of the planets that are capable of sustaining life does life actually evolve?
Answer: Current estimates range from 100% (where life can evolve it will) down to close to 0%.

I am glad to see you are really thinking about this. To derive a reasonable value for ne,
we select what seems to be a reasonable "life" zone, ergo, liquid water.
(Until we know
life can be very different than on Earth, we dont go crazy, cause this aint Ufology.)
As you noted, ne and fl are
closely related. A best guess for ne is to look at the percentage of stars that would have
planets in a habitable zone that is not being zapped by what we believe to be lethal radiation
of various sorts.
fl would then be a fraction of those planets, based upon our knowledge of
our own system, that contain life. I say 10 percent is overly optimistic for ne but that was what
was used in the example. If you want to say 100 percent, I need to hear your reasoning for
how there would be habitable planets around dead stars, neutron stars, black holes, supernovas,
red giants that have swallowed their habitable zone, and etc.....
"current estimates range from 100 % down to 0 %."
And in the equation, thats a multiplier of 1, for 100 %, and a decimal for less than 100 %.
You never get to use the 100 as the multiplier (smirk)

It's what opened me,a lifetime skeptic,up the possibility of alien visitation. While it didn't totally convince me it did lead me to do some research and after finding and reading cover to cover a book called Humanity's Extraterrestrial Origins I have little if any doubt that aliens visited/visit us rather frequently.
