Okay, reading through the answers will possibly make you more confused than you already are. Which I can't blame you as everyone believes in something and that thing isn't the same for everyone, otherwise we will all be the same persons which cannot be the case.
Anyway, you being a Christian is an ongoing process and you believing in anything is also an ongoing and a changing process. You might believe in one thing today and be totally convinced otherwise the next. Anybody saying that such and such is idiotic for believing this or that and claiming they are much more intelligent than another because they believe something that they have heard or have read something that was written by somebody else is also idiotic.
Thus, having said all this, do not just believe anything said by any Tom, Dick and Harry but test everything on your own, ask other's opinions (especially those you trust) but also look within yourself to know and discern all these things.
And to answer, yes, it can entirely be possible to be a Christian and believe in evolution. There are many different kinds of Christians anyway as there are kinds of evolutions.
You may or may not take Genesis literally, and the choice is entirely up to you, it is for this type of freedom that Jesus have set you free in the first place. But if you call yourself a Christian you should at least try to read the Bible from cover to cover at least once in your lifetime.
