@Mame,
No, it's not.
The churches and temples are a control thing. There is a God. Read the Old Testament but skip the law part. In fact, read only the parts that involve actual people.
You'll find that this is a story of a relationship. You can do perfectly well skipping church, and focusing on that. But then I found I was lonely. So I went to church but mostly igbored the minister. The minister btw is often a paid shill for the state.
Read the book Why Priests? A Failed Tradition. It talks about how the church has failed the people with its leadership. But this is not true of God. How do I know this? Okay, ask yourself several questions.
1. Why am I here? As simple as this question sounds, the atheist and nihilist have no purpose at all for life. In fact, the whole of science cannot provide any dimple answer just "how am I here? " It can tell us the long string of geological and cosmic events that caused a planet fit for producing life. But it's kinda funny to think that all of that happened on its own without life being planned as an end result. In fact, it really doesn't make any sense. The secular science is also a control system, btw. I say secular science because there are scientific types that nonetheless quietly believe in their faith. It tells you that you are an insignificant speck in a universe much bigger than you, and which doesn't care about you. This so called universe went and created someone like you from countless generations of evolution, but the abuser, I mean the scientist tells us how we are worthless.
2. Why has every civilized culture worshipped something? The ancient people worshipped the natural world, Egyptians and Romans worshipped gods, Jews and Christians worshipped God, and so on. You can say that it's a state thing, but that brings us to the next question.
3. Would you die for your faith? Early church did not believe in Hell. This is a control thing. Yet against their own government, they were willing to die for what they believed in. They obeyed the laws until the laws decided to do away with them for no good reason. If religion is really a state control thing, why do people in the past resist their governments, knowing full well that it will bring death on their own heads?
4. Who is Jesus? That seems like a messed up question if you already don't believe in God. But consider this. You say religion is a control thing. But this man came at a time where secular Roman state enacted high taxes and interference in people's lives. Every government without religion (Nazi Germany, Communist Russia and China, etc) starts to self destruct. When the majority of people think they can deal with problems by killing them, they elect leaders who do just that. And this was what was happening, Rome was a system that killed people for money. This was also a time when the religion of the day was crazed, giving laws that had nothing to do with actual goodness, and everything to do with following stupid rules. Jesus heals on the Sabbath, he doesn't wash his hands, he eats and talks with Those People. He cares about actual goodness and making people feel welcome. What is the purpose of this man, who is willing to give everything so that people have a better life?
