Consider the number of planets orbiting those stars and the high probability of life elsewhere in the universe.
Does that blow your mind or what?

I don't buy it. Scientists can't even confirm that human actions are causing the globe to warm, but they're stating they know how many stars are in the universe? Nope.

You're a buzzkill. Move along.
kinda makes it seem crazy to say that NONE have any planets that have any sort of intelligent life on them.

What makes you think there's a high probability of life on another planet? Even if another planet had perfect conditions... a stable atmosphere, correct weather, a stable star, etc... Where are the life-forms going to come from? I'd guess the Earth is like a 1 in a googolplex event. Keep in mind the Universe is not infinite. If it were, then outside life would be a certainty, but this isn't true.

Why do people believe in ET, but not Bigfoot?

The probability is somewhere between zero and one, inclusive. This does not blow my mind.
You have absolutely no idea if there are zero or billions of other intelligent life forms in the universe. Absolutely zero idea.
Yeah we really do have no idea at this stage, but I bet we will have a much better idea in 50 years. By then hopefully we will have sent some very capable probes to search for microbial life on Europa, Titan, and Enceladus, (moons of Jupiter and Saturn thought to be able to harbor life) and we should also have much better capabilities for exoplanet spectroscopy (which will allow us to determine if say, photosynthesis is occurring on a distant planet).
If we find any type of life anywhere in this little bubble that we are capable of surveying, the only logical conclusion would be that the universe is crawling with the stuff. But then you would still run into issues like the Fermi Paradox if you tried to stretch that into assuming advanced and even intelligent life must also be all over the place.
But I think it's exciting that we are on that threshold where we are starting to be able to take real steps towards figuring out if we are alone. I hope the 50-80 years I've (hopefully) got left is enough to see some real progress made.

You must be pretty young. I'll be lucky to see another 40 years. And yes, it is an exciting time. We will almost certainly have a much better idea in 50 years.
Maybe there are no stars. Maybe what we think are stars are just reflections of the grains of sand.
How would one go about guesstimating the number of grains of sand in all the oceans and deserts on the planet? Seems an impossible task
The light from the stars is merely the reflection of the earth's sand in your eyes. Until I saw your eyes I truly did not understand the beauty of the universe. Wanna get out of here?
I agree. We can't even come to a consensus on the true cause of the warming Earth, but we can determine how many grains of sand are on the planet? C'mon.
how disappointed would everyone here be if the night sky we see is actually just a big black blanket with holes in it put there by the government
also, I think the OP read the other universe thread and then went to youtube and found this analogy on a video
Interesting conjecture! If the night sky is indeed a blanket with holes in it, what is the light source that we see as "stars"?

a giant pair of nostrils with light bulbs in them
You had me with the blanket thing. But, don't you think the nostril idea is a bit outlandish?

Actually, this would be a rather trivial task.
(1) Determine average number of grains of sand in a cubic centimeter through sampling
(2) Determine approximate cubic centimeters of sand in oceans and desserts through measurement and simple extrapolation
(3) Multiply
"Absolutely zero idea" is not correct. You are suggesting that there may be a uniform distribution [0 life, billions]. Conditional probability. Probability of life on another planet and there are billions of other stars given that there is at least one planet with life (us). Given so many stars, there must be many planets at the right distance from their Star to support life. Given our existence, we know that the probability of life is >0. There may be no other life but I would say we have a good idea that there is other life.
