I have a theory
All thru Polynesia, micronesia, etc..., there were those guys, they HAD to keep going
No matter how nice the place they found, they STILL had to keep going
When they ended up in Hawai'i, even most of them said, " Ho kuz, we stay in da middle of NOWHEAH! No uddah lands fo miles and miles, tired already, I like go kaukau, den, SLEEP"
Still yet, there were a few who wanted to keep going. Here they were, on the only tiny dots of land in a whole CHUNK of area, and they still had the bug to go. So they said " Key den, mahus, you stay heah wit da wahines and style hair, we goin bag...LAYTAHS!!!!"
So on they went, jack diddly....on and on and on, and finally Rapa Nui. A teeny dot. If they thought the last islands they saw were tiny, well this one took the cake.
But they stayed. They knew this was the end point, and that the gods would take them from here, the final step, and set them asail upon the stars. So they waited
and waited
and waited
Finally one said, " Hey, we go stay come LONG TIME already! Thought bumbye god goin lift us up, but he nevah, we need to tell him were here, how we goin do that?"
"petroglyphs!"
"key den"
So they made petroglyphs. Made some on a rock. Made some on a cave
Made some on a tree. More more more. Everything was covered with petroglyphs
So they waited, and waited
and waited
"Ho kuz, we wen make CHOKE petroglyphs. how come they no come down? How come none of da gods like go stay come?"
"maybe they cant see from there"
" Den we goin make some BAMBOOCHA ones!!!"
SO they built gigantic statues, eyes up, to say LOOK AT ME!!! WERE WAITING!!!!
Thats my theory anyhow.
