Mbatian's prophecies vs. those of other Kenyan prophets

Mbatian predicted the coming of Europeans and the railway, similar to Syokimau (Kamba) and Mugo wa Kibiru (Kikuyu). What I find fascinating is that multiple prophets across different communities independently made similar predictions. Does this suggest a broader awareness of approaching change in pre-colonial East Africa? Perhaps traders from the coast had already spread news of European activities. Or do we attribute this to genuine prophetic ability? Let's discuss.
