Being uneducated about the Buddha's teaching, inexperienced in practice, and deluded are not good reasons to disbelieve in rebirth.
To learn the Dhamma thoroughly, and to gain mundane right view, let alone supramundane right view, is difficult — that is a given. If the Dhamma was easy to understand, the Buddha would not have been disinclined to teach it.
The rest has already been discussed at length in the Great Rebirth Thread, and doesn't need to be repeated here.
