When God created all the animals
People did not invent God. God has always been.
by ponies i hope that meant horses? and posiedon god of the sea created horses. there is no god of horses but, posiedon was the god to make them.
He(God for you) didn't.
Poseidon is the God of horses because he created them from the sea foam. Poseidon is the God of Horses, the sea and earthquakes
well, there was no real god or goddess of horses but Posiedon(he's a greek god though, sorry) created horses so he is probably the closest you'll get to a god/goddess of horses
GOD made horses
Ehh No it's impossible to invent a nature animal, and no again if you mean they were the first to use them.
No, God did.
Posiedon was the Greek god of the sea, but he was said to be creator of horses.
Poseidon, alternatively known as Neptune to the Romans, was the god of earthquakes. Please note that he made horses, not sea horses.
God created horses, as he did every animal.
That is not true. Hades was not associated with horses at all. Poseidon was because he was sometimes worshipped in the form of a horse at certain locales in Greece.
