It was all made up, why those people tend to think about how they are all so much above other living beigns on this planet(if anything human race is parasite but thats whole another story)? Human beings needed so called Gods for
a)controling less educated(well, let's just say stupid) masses
b)establishing moral code
c)obtaining material benefits from their acolytes(cults basically, we have so many now, if you look closely at what christian church, especially catholic is doing right now, at least in some countries, it fits just right into that one)
Let's go back to the roots of all religions, thousands of years ago and compare to religions we have now. Back then religion was made up to explain things they couldn't understand at all(due to their scientific ignorance) which we can perfectly explain nowdays. I really doubt they created all this religion stuff because they needed ,,caring father above,,. If you take close look at ancient religions, most(if not all) gods were vengeful(hell, we have that even in holy bible), didn't really care about fate of humanity, tried to manipulate fates of living beings on the planet for some enigmatic reasons. If you take a closer look at the hierarchy of ancient cultures we know from our history classes, or even some of the tribes we still have out there which are still cultivating their semi-savage rituals you could notice there's always someone - be it shaman, priest, whatever, that claims to be close with ,,god,, and tries to control people which are ,,not-so-close with god,,. This is one of main reasons for religion - control and manipulation. The worst thing is some of those religions tended to halt scientific progress, but that is logical, science endangers religion cause it has potential to reveal this bullshit, therefore they wanted to dampen it as much as they could.
It really doesn't take an atheist to come up with those conclusions, just some basic history classes and basic reasoning.
I won't even start with how many, many theists take their ,,holy scripts,, literally(,,if first few pages said there was god who made everything in few days and then he took a rest on the last day of the week then it IS what happened and thou shall not question it,,) instead of analysing them on higher level(yes, analysing text on level higher than literal is something they teach in fucking primary schools nowdays!). Even though I am an atheist I still think those texts are valuable piece of history(as are other serious writings from thousands of years ago) and therefore are worth analysing.
If we get onto topic of moral codes some might think religion is good, it is teaching kids moral codes so it has to be good right? Well right, but may I ask, why all this bullshit that comes with it? Killing is bad, stealing is bad, adultery is bad, and so on, but aren't those laws and rules we should get into our heads(well, we should at least) from our parents? Hell, in most even slightly civilised countries law regulations also forbid said things. So why do we keep polluting our children with all this nonsense like ,,thou shall not eat meat on fridays,, or ,,thou shall walk to the church every sunday,, etc, etc. We should want to implant moral values and codes into our children, not some made up bullshit from hundreds or thousands of years ago to make those religions look ,,more serious,, for people living back then. I believe we are living in times civilised enough(well, mostly) that we can agree that same moral values are, in general, common sense now, it's something we are(or at least should) suck up with milk from our mothers.
If anything, religion leans towards demoralising nowdays, Islam being perfect example, we had something like that with christianity also(crusades, etc), hell even nowdays, in some parts of our planet they are crucifying themselves(LOL) to prove their devotion. Question is, how does this serve humanity? If in a way that they are having chance to remove bad genes from the genepool(hello darwin's awards) they yeah, other than that?
I won't write much about c) because, well, it's thankfully not like that in all cases(but hell, I dare say it is in most, again, catholic church in mid-eastern europe comes up as an example, I know cause I live in mid-eastern europe). Instead, I will rant some about the need of having something after life people tend to have, and about having someone to look after them in their lives. I myself have accepted the fact that when I will die my remains will rot and I will be gone, cause I accept that I'm not that really above other living organisms on this planet, stuff is born and stuff dies, normal circle of life. Religious people tend not to accept it, they tend to think of themselves as above everything else on this planet(pretty egoistic in my opinion, given that some religions, not all, claim that animals have no souls). Given that we have solid proofs of dinosaur existence long before humankind, what happened to all those poor animals then? They all just ,,died,, there with no afterlife while ,,god,, was waiting for his ,,chosen,, race to gloriously emerge so they can die and come to his kingdom? Of course im generalising it just to christianity(cause I have most experience with it), but really, this is how most(if not all) religions work - they promise afterlife. Come to think if you analyse historic evidence you can say that belief in afterlife and act of burying dead had no roots in religion. Since the most primal religions(worshipping rocks and trees) were all built around nature, afterlife belief seems to have no connection to the first religions. If anything it seems to be incorporated into more modern religions to make them even stronger.
And last part of my rant(finally eh?) is the so popular nowdays science vs religion thing. Well first of all I find creationism hilarious(yes, I said it) cause it's basically same shit as theism wrapped with diffrent packcage so it would attempt to reach modern people(which are in general smarter, or more educated than majority of people from thousands of years ago). It's really funny that before there was no creationism(as it is in it's current form, where it tries to disconnect from any religion in particular but tries to claim that there is being called creator) before scientific revolutions of 20th and 21st century. Suddenly people trying to convert non-believers found themselves cornered as they realised their old-fashioned bullshit won't convince modern people so they had to made up another bullshit which is basically same thing, but steals scientific knowledge(notice how all those creationists in their debates come up with all this stuff that was discovered,examined or proven by science and claim them for their arguments). Modern civilisation is endangering the old order of theistic systems and they understand this.
