It's all too easy to be distracted by all the claims about what isn't evidence for evolution or about claims that dispute the details of evolution so that one misses what is evidence for evolution.
This page links to some resources that give an overview of some of the evidence, much of which, of course, contested by creationists. Specific claims and pieces of evidence are discussed throughout the rest of the website.
Always bear in mind that anything can be waved away with a 'Goddidit' argument, such is the nature of supernatural claims (and hence the use of naturalism).
Many creationists and the major creationist organizations now actually accept that evolution occurs, although they may downplay it by calling it 'speciation' or 'diversification' and claim that it happens only within 'kinds'. These creationists also claim that accelerated 'diversification' happened after the Flood and that it's only 'downward' evolution. Because of this, it tends to be not evidence for evolution that is sought but evidence for common ancestry (common descent). Therefore although common descent is a concept within evolutionary biology, this page includes resources for both.
Please follow up any questions these resources raise for you in the other sections of this site.
