By scientific method you mean logical processes, right? Aren't there more truth seeking processes that are not strictly subject to the scientific method?

And by truth you mean a limited understanding of the universe, right? Aren't there widely accepted models of reality that are not fully adequate in explaining phenomenon?

Atheism-is-Unstoppable

It won't happen. While most religions are declining Islam in expanding.

as older generations will die, so will their beliefs, eventually after 4/5 generations the religion and god concepts will be non existent, religion exists today because of the older generations that give money to the churches, new generations will give less and less money and eventually churches will start to close down and religion will finally be gone

You forgot to mention Hog & Magog, the last horn being blown and the return of the King, and I'm not taking about LoTR lol

PS the Dajjal won't leave everyone astray, only those who have no faith or those who are weak in their faith as they will not see the Dajjal for what he is and they will fall for his false miracles.those who don't fall for his tricks will be a minority and they will be on the run from him. They will seek protection from the 3 sanctuaries he cannot enter, the Harem in Mecca, Majids e Nabwi and Masjid Al Aqsa. 

Also by this time, the population of the world will be smaller than it is now due to WW3 killing off lots of people, Hog & Magog killing lots of people and the great famine that will prequel the arrival of the Dajjal. 

I also want to add that religion is mostly present in poor countries with nearly no education available. So you can also conclude that, the poorest the country is, the more religious it is. In correlation to this, atheism could grow if these countries would gain access to better economy and education.

Some rich countries are having a cycle of atheism, I agree, like Sweden. In other hands, the most powerful nation of the world is a very religious nation, the United States of America.

Also Japan, which is a very high tech society, 80% of the people worship shinto gods, ancestors and believe overall in the supernatural, which, granted, does no imply the acknowledge of a supreme being, but do realize that the world goes beyond the physical realm.

Some european countries do live their most atheistics eras yet, but I believe this may change very soon, with some form of revival in the faith, when even the young folk can discover faith by themselves, in some way or another.

The more a nation has in riches, the less they care for God, this is the absolute truth, but in my opinion it does not mean it will achieve a extreme. At some point, people rediscover the divine somehow, and even with all technological distractions, they find God once again. Time will tell if I am right or wrong.

Education. 

No, its not absolut truth look at rich countries like Saudi Arabia or Qatar Dubai and others people that simply have money still believe in Religion. Sweden, Denmark, Norway all those countries might be rich but the reason why they do not believe is like mentioned above education.  Thats the key to help people get over this delusion. If you are a critical thinker you can more easily rid yourself of the mental straightjacket that is religion. 

Well, America and Japan are very well educated, and they care for God. So is the case with Israel. Granted, the majority cares less because they have distractions and never really have problems or angst in which faith could help them or lead them into prayer.

But even so, education does not really do the trick, it just helps people that want some justification to forget God, since our education system worldwide is so antitheist, even teaching things that the scientifical comunity acknowledge as hoaxes 20 years ago, like the Lucie fossile or the common descent chart ( Haeckel's drawings)  and things like that.

Science can help one to not feel guilty for going away from God and that I understand.

But I often think about what Francis Bacon said (and many after repeated): a little amount of science makes a person go away from God, but a great amount of knowledge and science brings a person back to God.

Most people are afraid of diving deep into evidence that may show them God exists, and some theories are desesperate atempts to take God out of the equation, like the Multiverse Theory. Funny enough that this theory implies the existence of something beyond the physical realm.

I see many so called scients stating that they would go any route, as long as it does not imply a God. So, it is not even science anymore, because real science would not ignore a possibility. When it comes to a first cause, they rather make the problem bigger and more complex than to understand that God is a necessary constant in the variables of existence.

Anyways, the notion of faith and religion being something of yockos and idiots is false, it is just something that atheists say. A lot of very brilliant men and women are theists.
