I've heard there's evidence but every time I've asked for it I'm just given some dudes opinion or feelings about it.
Meanwhile people say oh the.bible, but everything in there that's actually measurable with science has been proven false, even the origin of our species.
In my experience, the people who say "where's the evidence?" don't actually go very far looking for any. And when any is presented, they immediately try to shoot it down or blow it off, much like we've talked about in this thread about certain people's attitude toward the supernatural.
If you're actually interested in understanding WHY some Christians believe what they believe, and understanding why people like myself who, despite not being Christian, feel that Christian faith can be reasonable, here's where I'd start:
From a Philosophical Perspective: Mere Christianity by CS Lewis
CS Lewis is best known as the author of The Chronicles of Narnia (and, as an aside, was good friends with JRR Tolkein), but beyond that he is also one of Christianity's best known apologists. He was an atheist who became a Christian after becoming convinced it was true. He called himself, during the first year of his conversion, "the unhappiest Christian in all of England" because he didn't WANT to be a Christian but converted anyway because he felt he couldn't deny the arguments for it.
Mere Christianity doesn't go into "hard evidence" but instead focuses on philosophical and logical arguments. It's an easy and enlightening read, as well as being a literary classic.

From a Scientific Perspective: The Language of God by Francis Collins
Collins is an intellectual monster. His accolades are too many to list, but a few include the Presidential Medal of Freedom and the National Medal of Science. He is best known for heading up the Human Genome Project, which mapped the human genome for the first time, in 2003. As with Lewis, he was an adult convert to Christianity and he wrote The Language of God because he wanted to show that "one can be intellectually in a rigorous position and argue that science and faith can be compatible." If you want to go deep into theistic evidence from a scientific perspective, this is a good book for that.

From a Journalistic Perspective: The Case for Christ by Lee Strobel
Lee Strobel gets a lot of shit sometimes, but I think it's mostly unwarranted. Just like with Lewis and Collins, Strobel started out a skeptic and became a believer later on. He approaches the subject as a journalist: Instead of presenting evidence from his own expertise, he interviews experts in various fields, including history, archaeology, textual criticism, etc, and allows them to present the case while he records it. This is a good all-around overview of the subject.
