My atheism

I will be asked why I am an atheist. And therefor I need to give this answer right away.

I like to explain my atheism with a scenario.

We are living on a small blue planet that orbits a G-type star at a distance of about 150 mil. kilometers. There need to be a loot of parameters balanced very well to allow for life on this planet. But however numerous those constraints on the existence of advanced civilizations are - the universe is sufficiently huge to make it certain that there are advanced civilizations somewhere.

I don't want to argue at this place for the likelihood of those. I know very well that many Christians deny that those civilizations exist because their creation was never mentioned in the bible. I still want to ask my Christian readers to go with the existence of those civilizations just for the sake of this argument.

When presented with aliens in most Science-Fiction series on TV you will see most likely aliens about as much developed as we humans are. They might be advanced by several hundred years, but you rarely see civilizations that are developed even more.
From the early agricultural beginnings in Egypt to modern day you can roughly tell that the age of our civilization is 10,000 years. (or 6000 years if you committed to biblical creationism). Giving that there is no point of self-destruction in which every civilization when it reaches a certain point of development destroys itself there could be aliens whose civilization is millions of years old.

What would also mean that they are technologically advanced to a point where their abilities would seem magical or divine to us.

Should we therefor pack gold, silver, diamonds and things of worth into a rocket and shoot it into space?

My answer to it is clearly no, and I think most of my readers will agree.

Firstly, we don't know in which direction to shoot the rocket.

Secondly, we don't know whether gold, silver, diamonds and things that seem precious to us are of use for such a civilization.

Thirdly, the aliens never asked for it - even if, (like some UFO-scientists may claim) they did it in a way that the evidence for this is in modern days highly disputable. (to put is mildly)

Fourthly, we don't know whether our supply reaching one civilization wouldn't enrage another one.

Therefor the waste of shooting rockets loaded with valuables and the waste of time to do that isn't justified by any reason.

Now, after setting that up let us turn to theism.

Is it justified to send valuables to any kind of Gods?
And there are sent many valuables to God. Go to Europe and look at the cathedrals. Go to the muslim world and look at the mosques. Even Buddhism can be exceedingly wasteful. Simply research the Swedagon Pagoda in Burma.
Beyond the apparent things done for religion and massive amounts of valuables given to religious purposes, there is an enormous amount of time spent for those purposes - in every religion.

I reason against those sacrifices with the very same arguments than with shooting rockets into the sky.

Firstly, we don't know in which direction to shoot the rocket.

And we also don't know which God to give our time and money to.

Secondly, we don't know whether gold, silver, diamonds and things that seem valuable to us are of use for such a civilization.

How do we know that prayers are of use for God? How can anything we could give to a God be of use for him, her,it or them? God, if existent, could have anything he, she, it or they could want. What exactly do you think he, she, it or they needs from you?

Thirdly, the aliens never asked for it - even if (like some UFO-scientist may claim) they did it in a way that the evidence for this is in modern days highly disputable. (to put is mildly)

It is said that God asked for it. In the Bible, Quran or the Veden. But the origin of those books is also disputable. Supposing this God would be almighty we could expect there to be much better evidences for the demands. Extraordinary demands also need extraordinary proves.
Let's look at the bible for example.
If we go by the best estimations the first gospel was written 10 years after the death of Jesus. Jesus could have turned water into ink, sand into paper and made one of his disciples write his words and deeds down as they were said and done if he was the son of God. But: It seems that he trusted the most important things ever said and done into the hands of 10 years of gossip.
Even if those words and deeds were written down by a first hand witness; 10 years are still a long time. Anyone who doesn't believe that is asked at this point to write down what he or she did 10 years ago.

Fourthly, we don't know whether our supply reaching one civilization wouldn't enrage another one.

That's a really big problem with Gods. You sacrifice to one - you enrage another.

Conclusion:

Just like the aliens would need to show up and ask for their rockets full of gold and diamonds - God would also need to show some provable sort of interaction with this world that would be enough to justify the enormous amount of sacrifice he, she, it or they demand.

The ambition of a lot of atheists or agnostics to disprove that he, she, it or they don't exist is leading nowhere. The lack of provable interaction itself justifies a de-facto atheism completely. I don't discard the possibility of the existence of a God or Gods but I discard the necessity to give anything to them.
