What are the odds that extraterrestrial life exists?

The galaxy, and we presume the universe, is full of life. Over the centuries, your planet was a curious place to visit once or twice and was not considered very interesting . Sure, your wars showed us how undeveloped you are as a species. Your infantile,(in cosmic terms) dependence on god concepts does not bode well for you and neither does your penchant to breed beyond your planet's ability to sustain you. We are now showing an interest in you because it is not often that we get to observe a species commit suicide. You are so close to maturing as a sentient species and it will be a shame to see you kill yourselves. There are just not enough of you becoming rational enough to force the issue. You let the least among you determine your fate, so be it.

This question has vexed physicists and astronomers for more than a Millenia. There is now a branch of theoretical astronomy devoted to this very idea. The numbers alone are staggering. For our Universe there are over a hundred million galaxies each of which has over a hundred million stars, doing the math makes overwhelming numbers for the argument for the existence of other life more than a possibility. As well as this there is the possibility that other life is not carbon based, it could be silicon based as silicon is the most abundant substance in our universe. I'd like to think we aren't alone here but proving it is a little difficult at present

The odds are rather good considering all the stars in the night sky may very well have planets. If only one percent of the stars have planets that's still in the hundred thousands of possible planets and some percentage must have life. the third stone from Sol dose so why not more.

this question has vexed physicists and astronomers for extra effective acceptable than a Millenia. there is now a branch of theoretical astronomy dedicated to this very concept. The numbers on my own are techniques-blowing. For our Universe there are over a hundred million galaxies each and each of which has over a hundred million stars, doing the mathematics makes overwhelming numbers for the argument for the life of diverse life extra effective acceptable than a probability. besides as this there is the possibility that diverse life isn't carbon based, it may desire to be silicon based as silicon is the main ample substance in our universe. i could prefer to think of of we at the instant are not on my own suitable here yet proving it relatively is a sprint complicated at modern

well the chances are prety slim, but really unkown. Thier are estimated to be over 100,000,000,000 (100 billion) glaxies in the universe, you guesss that maybe 25% have about 8-10 planets and then maybe about 2% have life and then another .25% have inteligant life with another ,0125 having life as inteligant or more inteligant than ours its really so small a number or so unkown a number that it cant be calculated.

Nearly 100%

When you calculate the number of galaxies, stars, planets around each star the number is so massive that the probability of us being the only life sustaining planet falls to almost 0%

Virtually nil. The chances of the right circumstances happening to create and maintain life are considered so small it is very likely there isn't any other life in the Universe. If there is, they believe it is likely to not exceed on chance per Galaxy.

It's almost impossible to calculate, we haven't really examined any other rocky planets outside the solar system. It would be a highly inaccurate guess.

Since we have never had actual proof, the chances are pretty close to zero. As a christian i would say that there is absolutly no chance, however as a scientist, i would say that it is unlikely however there are always factors that could change.
