No, Eren is not the Father. Historia only asked Eren about herself getting pregnant in order to not become the next Beast Titan.

Everyone is looking too much into it, the same way they looked too much into Zeke and Eren working together in the beginning, or the person in the window being Eren when it was in reality Kieth Shadis.

Besides, there are many fan translations that are inaccurate, very similarly to how in one chapter Zeke claimed to have a son but then was later discovered to be a mistranslation.
