Help w/ making a last lullaby that started a religion

My universe is a fantasy(duh) where instead of having a planet, it's the corpse of a giant(also the only giant but that's not too relevant). In this universe, the current world was not the first, and the first world went through an end of the world scenario(cosmic horror type stuff). My idea is that, instead of having the phrase "Oh God", they have "Oh Maya". This is because the only thing left of the first world was a lullaby written by a soldier for his young daughter, Maya. A lullaby that she would never get to read. People from the new world found pieces of the lullaby(how the pieces survived I don't know), and believed it to be written as a plea to to a god(called Maya) to save them(or to bring about their end there are a few different interpretations). if they had the whole thing, they would know that it was simply a last lullaby from a soldier to his daughter, asking her to not cry, and that it was all going to be OK(it obviously wasn't, cus the world ended, but still)

I do have a few lyrics and pieces of lyrics, so I will put these below in italics and bold.

When the eyes, in the skies, open wide, Oh Maya

Please, do not cry, my-y dear, my Maya

That was all I could remember off the top of my head

I would greatly appreciate any help and suggestions to create this lullaby. I will make sure to give credit and thanks where it's due and will add a link if I finish it. I am looking forward to being able to share it w/ you all!

I suggest adding a few more phrases that the common folk speak than just "Oh Maya". And if it's supposed to be a lullaby for a child, but it's not obvious if the people have only a few verses, then make it obvious if they have the whole poem. Such as not naming the baby Maya, but just "my child" or "my baby", but keeping the same verse length. Something along the lines of

Close your eyes, those blue stars,
sleep well and dream, my baby girl.
Pick a dream from the set of jars,
Nothing will hurt you, my darling pearl.

When the eyes in the skies open wide, Oh Maya
Watching over the lands and seas.
Please do not cry, my dear, my Maya,
Tears will fade in the morning breeze.

Having this sort of mixture of daughter-only and Maya-only will surely have caused the two halves to slowly separate from each other over the ages. But keeping both with the relatively same tempo, so that when a person knows the whole lullaby it can be identified as a verse and chorus.

I only want her to be referred to as Maya tho. also the whole lullaby in intended to, if someone has at least most of the available pieces, show a mostly clear image of what happened at the end of the world(should have specified that, sory). maybe Maya was an adult who would appreciate that sort of thing idk.

 i do like this idea and have been trying to find an alternative for the phrase "By the Gods"
