More on ancient Maori hieroglyphic script

The ancient Maori hieroglyph referred to here is that recorded by Richard Taylor in 1861. In my view the sloping straight line signifies the flight path of the space ship. The human figure with the "sperm" has sloping eyes, akin to an alien's, unlike the other two human figures.

I believe the message transmitted is something like:

"We sailed (down the incline) from the twin star [6] in the constellation [4] where we lived as earth-bound (backward-pointing feet) birds [15] under our (smaller/more distant) sun  [6]. We embarked onto our spaceship [7] and travelled down past the stars [3]. We first landed on the moon [2] before finally disembarking [8] here on earth, where we used our sperm [11] to produce working human beings [13,14] under your sun [9] and rain [12]."

Surely there's information here?

Unless it was severely distorted by those who recorded it, the ancient hieroglyphic script of the Maori, found on Pitcairn's island suggests some interesting things. At the top right side there is a cross, which could mean the southern cross constellation or some other constellation such as the Pleiades. Near the cross there is, possibly a double star system.

What is most interesting is the human at the extreme left end of the downward incline. What some may have interpreted to be a tail may actually be a sperm. So the whole picture resonates with the Sumerian account of man's creation, in my opinion. Unfortunately I am not in a position to read what the listed authors have already written about the hieroglyphs.
