You have made the claim that we are made of substances that are common in the universe. Indeed, it was from the dust of the earth that God made us.
As Neil Degrasse Tyson points out: "“The four most common chemically active elements in the universe—hydrogen, oxygen, carbon, and nitrogen—are the four most common elements of life on Earth. We are not simply in the universe. The universe is in us.”
Not dust -- the elements of the universe. Get some science, it's not painful -- just takes a little more work than being gullible.
You have made a claim that thousands of planets could support life. You may be right about that. But I would like to see your list of planets that can support life, and your evidence that each of them can indeed support life.
You really are funny. You happily believe the tenets of your religion in the absence of any real evidence, but also in the presence of very real, and in my view catastrophic, evidence against, in the form of ignorance and contradiction. And yet, when the evidence before you is "life is made of the stuff of the universe, and the universe is filled with an unfathomable abundance of that stuff," and further that life has indeed happened at least once (that would be here, I hope you remember), you have trouble believing that it has pretty much certainly appeared elsewhere.
You only believe the fables of your childhood, is that it?
I will admit, there seems to be a lot of stars.
Yes, we can be quite certain that life has become emergent on at least one planet. I it is quite misguided however to suggest that life could have originated on any of the billions and billions of other stars. Life just doesn't seem to originate on stars. I think the climate on stars pretty much prohibits life from existing on them.
Now you are being deliberately idiotic. Nobody said life originated on stars. It didn't here -- it originated on a planet orbiting a star at a distance conducive to conditions that would support life. The lowest estimate for the number of potentially habitable planets in the universe that I am presently aware of (by scientists who do the hard work of studying the matter) is on the order of 100 BILLION.
Again, you do not know what caused life to exist here on this earth, so you certainly cannot say where life originates, let alone suggest that you can determine the probabilities of life existing somewhere else.
Now this might get you into trouble -- what if, just what if, science learns in the near future precisely how life can originate in the presence of conditions like those on earth some 3 1/2 billion years ago. Will you then admit that it can happen without God waving his magic wand?
Probably not, I predict.
