Again billions to one in favor of life/

That is a remarkably hard question to answer.
In order to answer it the factors determine the existence of life must be quantified, and then their distribution in all places "beyond earth" must also be known. At that point statistics can give a more meaningful estimate.
Without a more specific definition of what qualifies as life, or what beyond earth means I am going to assume that you mean beings of similar nature of intelligence, and ability to communicate that intelligence as "modern" human beings that are on "nearby" extra-solar planets.
Seti hasn't detected any, so they are either nonexistent, farther away, not using our technology, or have a fundamentally different idea of assonance and dissonance than we do.

A scientist named Dr. Frank Drake actually tackled this question before and came up with an equation to determine the probability of life on earth. I would type it out here, but there's a lot of subscripts and stuff, if you want to see it check out the link here:

Basically, the statistical odds are real low, but not completely impossible.

There's probably a 1% chance that there is an amoeba-like creature on a planet 50 trillion light years from Earth.

50% if you believe that there is a mirror image of the universe as we know it ! No one knows what is in and beyond a 'black hole' - we haven't been there yet ! If it's true there will be a 'twin' earth out there with life form on it !

Purely incalculable.
There's an equation for figuring it called the Drake Equation. Search for it on space.com. Notice that it's just several variables multiplied together, but nobody has any clue the true numeric value of most of those variables- some may be close to unity, that is equal to one, but others may be infinitesimally small.

I would say evidence of previous life 100%, actual living creatures, given the actual known vast quantities of time and space, probably 2-4%. A continual melting pot might not really be correct; such that homeostasis occurs over and over again. We know black holes don't dissipate into galaxies.

Don't believe you could accurately answer that one, you would need to make major (deeming the result inaccurate, in my opinion) assumptions of how many suns, planets that can sustain 'life' (which would be hard to define, think Aliens and you'll know intellegent life may exist unlike we know it), solar systems, etc.. and calculate the probability life exists. I just don't think an accurate answer can be derived.

there is a 100% chance for life beyond earth
that's because we live in one galexy out of the other millions of other galexies on our universe and they all have their own suns in the middle of their galexies. so, there is bound to be some form of life out there in those billions of other planets

It is beyond belief that there isn't life elsewhere. Way too many chances.
