What I dont understand is this piece of logic:
It's impossible that the univers exists by and of itself, so therefore there must have been a God that created the universe.
But, when you apply the same logic to god, and ask who then created God, they say "Oh, no, no, no, no, no, noone created God, he just exists because he is God".
Double standards. If it's possible that God just exists why isnt it possible that the universe just exists, without anyone creating it?
I had some issues with this too. Now I interpret it as follows. On the fundamental level, the concept of god is no different from the concept of the most fundamental physical law of nature. Both can be viewed as entities that have no space/time-character, so they must transcend the universe (for the universe is defined by space and time). The difference is, one is static (natural law), and one is variable, or has a "personality" as some like to call it (god).
The starting point is that a)the universe has a beginning (this is commonly accepted as a fact nowadays) and that b) everything that we can observe and that has a beginning (thus, the universe also) is subject to the principle of causality. So, if you want to define something that caused the universe, it must obviously transcend the universe (space and time), and thus also transcend the principle of causality.
Anybody feel free to question what I just said, because I just made it up myself.
But without god, the universe created us. So what's the difference, one thing that we can't explain or another thing we can't.
Assuming that by "universe" you mean "the most fundamental law of nature":not much if you ask me.
Name one thing that exist and you have no evidence for it.
You're asking a very weird question, because the basis for assuming something exists is of course evidence. Anyhow, I'll show you why your statement is a fallacy, by giving an example. Before Thompson discovered the electron there was no evidence for subatomic particles. So, if your reasoning is true, people back then could have rightly said subatomic particles do not exist.
not correct. There is a decent theory that explains very well the beginning of the univers. It's called big bang and there is more evidence for it being true by the magnitude of 1000 than for existence of god. IF you can explain something using what is known (ie natural), unknown (or supernatural) is unnecessary.
Big Bang Theory doesn't necessarily exclude the existence of god, because it doesn't explain what caused this big bang itself. Unless you're assuming that the most fundamental natural law is just that big bangs happen with some kind of regularity.
Scientists will
keep their mind open, but they will not ignore the evidence (or lack of it

)
All I'm trying to point out is that this is the only fair position to take. Neither 1 or 7 can be called reasonable.
