Atheists do not hate religion. But believers and worshipers always hated thinking people, that's why they burned them at bonfires.
There are many people that apply thinking in scientific style to religion. When they do, they find that the Christian religion is reality.
For example. There are in the range of 25,000 ancient, hand-copied Bible manuscripts. Yet there are few from any other religion. So what if many of the 25,000 are translations? If the other religions or philosophies were important, they would have been translated way more times than the few dozen or less that they were.
In addition, there were almost no times in the history of the Bible that it wasn't being copied or translated by someone. Yet all the other religious and philosophical documents had gigantic gaps in time where nobody was copying them or translating them. Then someone found a copy of one of those in some old library, and made a new hand-written copy of it... or a translation.
The odds that the Bible would have been in constant copy or translating, while none of the other documents were, defies the laws of simple logic. There is Divine movement behind the Bible.
There is also overwhelming evidence showing that the earth is in fact much older than the bible claims not to mention the universe. The bible is also a really bad and evil book, all the slavery, rape and death, no god would have allowed such book to be a representation of him.
I can read Professor Joe's book that says that the earth is probably 4 billion years old. Then I can write my book that says that the earth is 4 billion years old. Then you can believe what I say. But until you find out what Professor Joe said, and why he said it, you don't really know how old the earth is, even if you think you know.
None of the scientists who personally attempt to determine the age of the earth has said in factual terms that he knows how old it is. None of them provide conclusive evidence. They all say in one way or another that they don't really know, but that they think this or that.
The Bible is eye witnesses to power. And the power they witnessed was recorded in the Bible in ways that show us that the earth is less than 6200 years old -

Why would God do this or that? Who knows? But there is power in the Bible. It can be seen in the detailed history of the Bible, the strength of the traditions of Israel who uphold the Old Testament, and in the prophesies that the Bible makes and are fulfilled in general history. The eye witness accounts in the Bible are better than all the guesses of the scientists of today.
