There are many aspects of Christianity that non-believers might find unpalatable.
There are also key aspects and less improtant ones.
Needless to say key ones would include how to be Saved.
Issues such as a young-earth creation might be a stumbling block, however believing in dinosaurs disproving the Bible equally could do.
Whilst it may be impractical for us to ever prove to 100% that Creation is true, as there is always a speculative answer otherwise, we can at least point out Creation's high probability and that it aligns with the Bible and the concept of death after sin.
