I think that g4 is telling us something about how we got here, and the’re some famous quotes from well known scientists(mainly Neil deGrasse Tyson and Carl Sagan) the planets, the stars, the galaxies, we ourselves and all of life, THE SAME STAR STUFF, saying about where we come from and when, I believe g4 is telling us that we are made of light, we are made from this.
 

 
The stars is what made us billions of years ago through nuclear fusion and supernovas, possibly before the earth and even the solar system was around, maybe even the milky way galaxy, and the reason why these characters are similar, it’s because they represent:light.
