"I wish someone had just told me the truth right up front, as..." — Ernest Cline quote meaning

I wish someone had just told me the truth right up front, as soon as I was old enough to understand it. I wish someone had just said: “Here’s the deal, Wade. You’re something called a ‘human being.’ That’s a really smart kind of animal. Like every other animal on this planet, we’re descended from a single-celled organism that lived millions of years ago. This happened by a process called evolution, and you’ll learn more about it But trust me, that’s really how we all got here. There’s proof of it everywhere, buried in the rocks. That story you heard? About how we were all created by a super-powerful dude named God who lives up in the sky? Total bullshit. The whole God thing is actually an ancient fairy tale that people have been telling one another for thousands of years. We made it all up. Like Santa Claus and the Easter Bunny. “Oh, and by the way … there’s no Santa Claus or Easter Bunny. Also bullshit. Sorry, kid Deal with it.
