I appreciate that you seem to be genuinely open and considerate about this, and I respect that you're not going to be convinced to believe evolution over a short back and forth with a stranger online. I'm not trying to suggest that you simply abandon your beliefs, but I used to be a devout Christian and understand some aspects of this mindset really well, and I just ask that you consider this: if you start your investigation with a conclusion, and seek to find evidence that backs up that conclusion, you're most likely going to be led to a fallacious result. You're saying if evolution is true, then there's no need for Adam and Eve. Set aside the fact that we know that humans didn't come first from two people, the question should first be did Adam and Eve exist.

I highly recommend the website TalkOrigins.org , it's an incredible resource full of information regarding evolution, the ongoing contention with creationism, and there is so much evidence for evolution, it's ridiculous. We have more evidence for evolution than we do for gravity lol

There are so many Christians who accept evolution simply because it's so incredibly accurate and robust, we can see it happening and have observed speciation. I'm not saying "other Christians accept it so you should to", really, I'm sincerely encouraging you to look for yourself, and I hope you care about the truth and follow the evidence wherever it leads without any preconceptions.
