Well.... we know that our solar system is about 4.6 billion years old. This has been established scientifically by analyzing the nuclear decay of certain isotopes that decay at a very predictable rate. We also know that the universe has existed for about 13.8 billion years. This has been measured by observing the temperature of the oldest detectable white dwarf stars. These stars undergo a very predictable life span and cool at a predictable rate. By extrapolation you can "roll back" this process mathematically and determine that the oldest things we can detect in the universe are about 13.8 billion years old and therefore the universe itself must be at least that old.
But you weren't there! This invalidates everything you just explained, therefore the explanation that the FSM has created everything becomes the only true explanation
by default.
Or something.
Good thing for us, however, that it did because if you change any of these primary parameters even a tiny bit, the universe and everything in it as we know it, would not exist. Was this an act of God or a REALLY lucky roll of the dice.....? Einstein, who was the father of quantum physics, said that he thought it must have been God.
Two things here. Einstein did talk about god quite a bit, but he wasn't actually a theist. He was a deist or perhaps a pantheist at best. He definitely did not believe in a personal god, like the Christian or the Jewish god. He said so himself.
Secondly, the argument about the laws and constants of nature being "fine tuned" can often be heard, but it's a bit of a red herring. For once, there's no consensus about this. Depending on who you ask, the laws and constants of nature can be changed quite a lot before it making any significant difference. The other thing is that even if we were to assume that the slightest change would make the biggest difference, we still couldn't tell what kind of difference it would make. All we could say is that things would be different, but we can't say how. We can say that life
as we know it couldn't exist, but that doesn't mean that no life at all could exist. The fact is that we don't have another universe with different laws and constants of nature to look at. We have to plead ignorance and maybe we will never know.
Maybe to a Roman ages monk, the moon did seem like a sign from God. I don't doubt that. I mean... it had to be there for a reason, right? How would an ancient monk explain night and day if he wasn't even aware that the earth was a planet, let along a spherical one.... and that it was spinning around at high speed like a top and twirling around the sun at even higher speed...... ?
To be honest, I think a Roman ages monk might have thought you were certifiably insane if you had told him that. These things were being observed but none of it could be explained by the body of knowledge we had at the time..... Best guess at the time was clearly that some higher power (since we knew that humans were not causing it) must have had a hand it in. It was a bloody good guess if you ask me. God created the heavens and the earth, day and night, the sun and moon and *presto* it all fits its own internal logic and the questions are neatly answered. A hell of a good theory. it was later proven wrong but as a starting point it gave people a way to understand the universe and it worked.
This is known as the "god of the gaps," an argument from ignorance. And yes, people still do this today. Primarily religious ones, especially creationists, but it's a tempting pitfall for everybody.
Abiogenesis? Science doesn't have a sufficiently proven answer, therefore god must have done it.
The big bang is another commonly encountered one, but from those who aren't young earth creationists. (Another instance of how Christians can't even agree among themselves about their supposedly divinely revealed truth.) What happened before the big bang? What caused it? We don't know, therefore god did it.
The problem with this type of reasoning is (other than that it's logically incorrect) that its track record is exceptionally bad. Throughout history, people have encountered mysteries, things they couldn't explain. And invariably there were people resorting to supernatural explanations. And invariably, they turned out to be wrong. The actual answer turned out to be not magic. Every single time.
Thunder and lightning? Nope, not Zeus throwing down lightning bolts, but electricity. Tide goes in, tide goes out, you can't explain that. Nope, not Neptune doing it, but gravity. Rainbows? Nope, not a sign from god, but light and raindrops. People falling over and shaking violently? Nope, not demons, but epilepsy. Lights moving in the sky in weird patterns? Nope, not gods moving stars around, but heliocentricity and planets. The list goes on.
Not once has the answer turned out to be anything supernatural.
And even under the assumption that the explanation of these two cited cases (abiogenesis and the big bag) is indeed something supernatural, it still wouldn't mean that any particular god did it. It could have been Odin, Zeus, Superman, the FSM, or the pile of magic rocks I have in my backyard.
On other subjects, I believe we still need religion. As I said before, science can explain HOW things work (to an extent) but people still long for direction in giving meaning to the life they have.
I'm gonna have to disagree with you there. Religion and its adherents or proponents are not in any way in a better position to talk about the meaning or purpose of life than scientists are, or your grandmother is for that matter. What do they know that the rest of us doesn't know? Nothing, other than religious doctrines and ancient myths that have no basis in reality at all.
Now I'm well aware that many people find comfort in religion, find comfort in the belief that somebody's looking out for them, that they'll see the deceased members of their family again in the future, that there's some higher purpose to life. But that doesn't say anything about the truth of that belief.
Is it beneficial to believe in a lie? Or is it better to try to find truth? Me personally, I want to believe as many true things and as few false things as possible. Personally I think that's a good way to go through life. But I understand that for some people, this might not be enough, and that they need some, uhm, superior guidance or whatever you want to call it. Religion seems to be an obvious solution in these cases (even though I would argue that it's still not beneficial to believe in a lie and that there's better options), but there's a problem.
Religion comes with a huge amount of baggage. It's comforting to believe that when you die, you'll see your family again. But what if they didn't go to heaven, but went to hell instead? How can you find comfort in that possibility? What if
you go to hell after you die? All it does is to perpetuate fear, and surely there can't be any comfort in fear. And this is just one example of the many problems that religion brings along.
