Are there any other ways to explain the existence of the constellation hydra?

I'm doing a project on the constellation hydra and i want to know if there are any other reasons to explain its existence besides the myth|||Constellations are images the ancients saw in the stars. The images have no reality. Different cultures will look at the same stars and come up with entirely different images. In reality constellations are only DIRECTIONS. The objects in a constellation are at wildly different distances. They have no real connection. They just happen to be in the same general area of the sky when viewed from Earth. Thats it. There is no mystery.|||The only other explanation for the 'existence' of the constellation Hydra is obvious... that's where the stars are.|||It was hokus-pokused by the same bozo who did you constellation .|||All the constellations are attempts by humans to "connect the dots" in meaningful ways. Different cultures see different patterns in the stars, and so have different constellations.





The constellation Hydra is basically a long chain of stars stretching across the sky, somewhat wavy in outline, which the ancient Greeks saw as a sea serpent, what they called a "Hydra." Not surprisingly, Hydra turns out to be the longest of the constellations, but it is also the largest in area. It's very hard to see in the city, but in a dark country sky, it really looks like a long snake, with a broad flat head (about half way between Procyon and Regulus) and a long long body snaking away to the southeast, below the constellations of Leo, Virgo, Crater, Corvus, and Libra.
