Big Bang theory is the outcome of Einstein's General Relativity. It is foundational to our understanding of modern cosmology. There is no reason to believe events prior to the big bang are supernatural. Both M-theory and quantum loop gravity theory have aspects of them that can be extended...
The Drake equation you cite is for the number of intelligent civilization not just life. This is a vastly different number than those that produce life. Even using your pessimistic numbers, which are do not address the observable data we have on earth, the number of planets supporting life in...
Your post was hard to follow but I think this is the core of your argument.
" It is the number of exact conditions that everything has to be in for life to exist that is astounding. "
It is not that astounding when we look at the scope of the Galaxy though. There are an estimated...
The area that you are discussing is abiogenesis, the transition from chemistry into biology. Currently there is no accepted theory on this subject. Arguing that 'accidents' are the explanation is therefore flawed since no explanation yet exists. Based on what we do know, however, we can see that...
"One cell is the cause of all life on earth."
This is almost certainly false. Life arose in a population of 'cells'. I use that term loosely since the first thing we would call alive would have been a very primitive organism compared to a cell found in a modern organism.
Nuclear weapons are like two combatants pointing guns at each others head. Arguing that your gun will blow out more of your enemies brains than his gun will blow out of yours is of no military or strategic value.
BTW if the debate is now about single common ancestor versus multiple ancestors then you are conceding that humans and chimp share a common ancestor? Since the argument Dawkins and Venter are having has to do with how life arose on the planet 3.5 billion years ago.
Venter does not dispute common descent of living organisms from the perspective of Humans sharing a common ancestor with Chimps rather does all of life spring of one seed or from several sources. He is in the several sources camp.
Here is his quote from your video...

"Biological evolution has taken 3.5 or 4 billion years to get us where we are." - Craig Venter
"Well, it's the changes that have taken place over these billions of years, but I think our studies have shown they're very different than what a lot of people thought of just minute changes leading...
I happily admit I have only an interested layman understanding of DNA, but still argue it exceeds yours.
"Today, the theory of evolution is an accepted fact for everyone but a fundamentalist minority, whose objections are based not on reasoning but on doctrinaire adherence to religious...
DNA is universal in life. The same components that make up a human's DNA appear in a rodents or even a bacteria. Further the codons that code for a certain amino acid in a human will code for the same amino acid in other organisms.
DNA absolutely changes over time. Ageing is a breakdown of DNA...
"After millions of years the fruit flies will still be fruit flies....
Any genetic changes will be minute & differing populations will be able to reproduce with each other....."
Outstanding!!
Now simply alter your time length. Since you accept changes occur extending your timeline increases...
