It seems that your evangelical colleagues are attacking in force, determined to either convert me or shout me down.
Oh, no, he called us evangelical. How can we ever come back from that?
* (1) Life exists. When the Earth formed, it did not. Ergo, it (a) formed naturally, (b) was formed by an intelligence, or (c) was deposited from outside (meteor strike). Since "formed naturally" violates the laws of probability and (c) doesn't address the basic issue, (b) becomes the most sensible theory.
The Earth formed 4.6 billion years ago. The earliest indirect signs of life on Earth are from 3.85 billion years ago, and those are not clear (they could be sedimentary rock, which would indicate life, they could be volcanic rock, in which case they would not indicate life). It took at least
700 million years for life to exist on Earth. And, again, those signs of life are not undisputed. The earliest direct signs of life we have, though even those have been contested, are from 3.5 billion years ago. That would mean more than a billion years of Earth without life. The oldest certain proof of life is from 1.9 billion years ago. So, it is quite possible, maybe even likely, that Earth existed for several billion years before life started.
Do you understand just how much time that is? None of us hear is older than a couple of decades, and it took
at least 700 million years, that's 70 million decades, for life to appear on Earth. And Earth is just one planet capable of sustaining life as we know it, we know of a couple for certain, we can assume there are a lot more that we have not discovered yet, of which quite a few might very well be older (and in cosmic sense that means millions or billions of years) than the Earth, in our galaxy alone, not even to speak of all those other galaxies like Andromeda or the Magellanic Clouds, Sculptor, Cartwheel, and that's just a couple of those we have a name for.
So how exactly is "formed naturally" violating the laws of probability?
* I'm not sure I get your next... you claim that you don't take science on faith. And yet, you presumably claim absolute conviction that it explains everything, with no room or need for the supernatural. Were that not the case, you would be an agnostic, not an atheist. Did you get confused by your own smoke and mirrors?
Do you even understand what science is? No, we don't take science on faith, because science isn't supposed to be taken on faith. Science is verifiable, you don't need faith in it, you can research it yourself, that's the whole point of it. We also know that there is a lot that science has not found an answer for yet, but through science, we learn more each and every second.
And if you still don't understand the difference between faith and confidence, then I'm guessing you don't want to understand it.
* I declared that atheism is a faith, and I hold to that. I never said that my personal beliefs were not. Belief in a Creator might be grounded in science, history, anecdote, personal experience, or a combination of the above... but it is still fundamentally, faith in the Unseen.
What you demand is that we proof a negative. Well, guess what, that's just about impossible. It is your claim, that (a) god exists, which is a positive, and should therefore be easier to proof. The burden of proof is therefore on the side of the positive claim, not the negative one.
