Where are lalafells from again?

Why you are saing that elezens were the only inhabitants of eorzea on the early 6th astral era? o_o

It's the very first thing you're told about Elezen in the Character Creator.

In former times, the Elezen were the sole inhabitants of Eorzea, claiming dominion over her. Traditionally a nomadic people, the tall, slender Elezen believed the realm to be theirs by divine right—a gift from the Twelve themselves. Unfortunately, this belief made the eventual appearance of the Hyur in their multitudes akin to an invasion, and a long history of conflict ensued.

The timing of the migratory waves is helped along by Albin the Ashen's Hunt flavor.

When the Hyuran tribe came to Thanalan some 800 years ago, Albin the Ashen was at the head of one of the columns.

And to bring it all home, Fernehalwes laid it out more clearly in an interview:

There are times when Eorzea has been more populated by one race over another and there will be conflict there. With the Hyur and Elezen, that’s very recent. In the Sixth Astral Era, the Elezen migrated in and in that era they were like, “We’re the first ones here!” even though they weren’t <...> And of course the pesky Hyur, who are everywhere, come in and the Elezen are like, “Oh, my god(s). We left you that whole continent up there! Why are you here!?” And the Lalafell come in and you have these cycles of clashing and moving and that gets ingrained in their society and their racial cultures.

In terms of the Lalafell, again... Belah'dia (Sixth Astral Era successor of Mhach, later split into Ul'dah and Sil'dih) evidently had Lalafell based on the tombs left by them in the ruins of Qarn and continuing Lalafellin leadership today. But do we know much about Mhachi races, yet? We have the hyur-ish statues in the Void Ark and a few names, but otherwise it's just the south seas Lalafells that teamed up with Mhach to take down Nym, that I remember.

The bottom line is that you have to look at historical information as a whole. Some of the conflicting information is the result of in-world ignorance.
