Answer (1):
Life is certain: we exist.
Answer (2):
I'm assuming that you already know that 'we exist', and that you are wondering what is the probability that other life exists.
Well there are two generic kinds of life. Intelligent and non-intelligent life. Personally I would say that we are intelligent life, whereas an amoeba would be non-intelligent life.
(These are very rough numbers) Given that that there are about 500 000 000 000 galaxies in the universe (500 billion) and about 400 000 000 000 stars in each galaxy (400 billion) that means there are about 200 000 000 000 000 000 000 000 stars in the universe (2x1023). That is 200 sextillion stars in the universe. That number in quite large to comprehend so to make it a bit more understandable. If 2x1023 were a number of seconds that would be about equal to 6300 trillion years. If that isn't helpful try this one, if you add up every single grain of sand on the entire earth, including all the deserts and all beaches there is about 1x1022 grains, which is about 20 times less than the number of stars in the sky! That being said, now consider that WE exist so that means that there is at minimum a 1 in 200 sextillionth probability that life exists. The probably that some form of life existing in the known universe (other than us) is pretty good.
Lets just take random probabilities to make a point. First we need to consider how many of the stars in the universe have planets orbiting them. Lets say there are 0.00000001% of all stars have planets orbiting them. That leaves us with 2 000 000 000 000 000 (2 quadrillion) stars with planets. Now we need to consider how many of those planets are "inhabitable" (meaning, Does it have the climate to support life? Temperatures aren't too extreme. And does it have the necessary ingredients such as water, oxygen, carbon dioxide, nitrogen, ...etc). Lets assume out of the 2 quadrillion stars with planets only 0.00000001%
have the necessary ingredients for life. This leaves us with 20 000 000 (20 million) stars with planets that are inhabitable. So out of 2 quadrillion stars total there are 20 million inhabitable planets.
So my opinion would be that it is probably that there is other life out there. Whether or not it is intelligent life is another issue.

Are there possibilities that life could also exist somewhere in the universe?
There are possibilities on all subjects. It doesn't matter how large the possibility is, but there are on every subject. As there is a possibility that we all go insane, and commit suicide on this hour... Even though the possibility of this is close to none, there still is a possibility, in any way you can look at it. There is a possibility that there is life in the universe other than ours. We didn't find out yet, and space agencies like NASA are busy researching this subject. The Kepler Space Telescope is busy looking out for planets bigger than ours. By the time we know if there is other life in the universe, it will be at leas some years in the future, most likely tens, or maybe even hundreds of years. But you never know, maybe there isn't...

What is the significance of the infinite earth theory in understanding the vastness of the universe?
The infinite earth theory suggests that there are countless Earth-like planets in the universe. This theory helps us grasp the immense size and diversity of the universe, showing that Earth is just one of many potential habitable worlds. It challenges our perception of Earth's uniqueness and highlights the vast possibilities for life beyond our planet.
Why are the theories of the origin of the universe not scientific law?
Not scientific law because there are too many possibilities, no-one can tell for sure.
