Your y=1/x formula could easily be y=1,000,000/x or y =0.00000001/x and still satisfy the limit in question. In other words the numerator in your equation could be any number and the answer would become that numerator.
So I could get any answer using the limit you chose.
ie..
y = 0.0000000001/x satisfies the lim that y approaches zero as x approaches infinity.
thus: x*y = x*(0.0000000001/x) = x/x = 0.0000000001
Your selection of one in the numerator for your particular thin air equation is bogus. And what are you trying to say with this equation? That having a non zero numerator implies that something will happen? That is certainly not what follows from having a non zero numerator, so the entire premise is flawed form its inception.
And your conditions are certainly NOT a valid for a purely random system where X EQUALS infinity and y EQUALS zero probability.
Ok....
The Nobel Prize-winning molecular biologist Jacques Monod wrote [1972:114]:
"The initial elementary events which open the way to evolution in the intensely conservative systems called living beings are microscopic, fortuitous, and totally unrelated to whatever may be their effects upon teleonomic functioning.
But once incorporated in the DNA structure, the accident -- essentially unpredictable because always singular -- will be mechanically and faithfully replicated and translated: that is to say, both multiplied and transposed into millions or thousands of millions of copies.
Drawn from the realm of pure chance, the accident enters into that of necessity, of the most implacable certainties. For natural selection operates at the macroscopic level, the level of organisms."
Yours and others denial of the random chance aspect of the "Random Mutations and Natural Selection" process, by claiming the natural selection process portion is not random totally flies in the the face of what the theory really claims. That random mutations do occur, and that they are the MAJOR portion of the theory that is required to drive the process. Its pure selective denial.
And certainly the abiogensys theories that almost always go along with the theory certainly maintain a spontaneous generation aspect that depend on random chance by their very nature.
OK

What do I even have to say about this statement which you haven't said for me.
Again...Intelligence whether front loaded or periodically tweaked is needed for the selection process to work.
I like Kelvin on this:
"Overwhelming strong proofs of intelligent and benevolent design lie around us ... The atheistic idea is so nonsensical that I cannot put it into words."
