What was the Greek Myth of how the Earth was created?

There’s several versions, so you’re not going to find one consistent version. In the beginning there was Chaos, pretty much all versions agree with that.

This is the version I am most familiar with

According to Greek mythology, in the beginning there was nothing. This was called Chaos. From this nothingness came light, Mother Earth (Gaia) and Sky (Uranus) were formed. From Gaia and Uranus came six twins known as the Titans. The six twin Titans were named Oceanus and Thethys, Coeos and Phoebe, Hyperion and Thea, Creos and Themis, Iapetos and Clymene, and finally Cronos and Rhea.

Gaia and Uranus also gave birth to three Cyclopes, three giants, each with fifty heads and one-hundred arms. Uranus disliked his offspring, so he forced them to return to their mother’s womb. The pain of carrying the numerous children angered Gaia, and she made a plan for revenge against Uranus. She called upon the Titans to help her. The youngest, Cronos (master of time), came to her aid. Cronos, with his mother’s help, created a sickle and cut off his father’s genitals when his father came to be with his mother.

Cronos cast the cut off genitals into the sea. According to some versions of the myth, the goddess Aphrodite was created from the blood that dropped into the sea. In addition some of the blood dropped on to the earth creating all types of scary offspring.

After defeating his father, Cronos married his sister Rhea. The two had six children: Hestia, Demeter, Hera, Hades, Poseidon and Zeus. Cronos, after each birth, swallowed the first five children because of a prophecy that climed one of his children would overthrow him. Rhea tricked Cronos with the sixth child. Zeus, instead of handing Cronos the child, she gave him a rock in a blanket. Cronos swallowed it believing it was the baby. Rhea then smuggled the baby Zeus to the island of Crete to be raised by nymphs. Later Zeus would return to defeat his father in the battle between the Olympians and the Titans. http://funadvice.com/r/be9niilrc4d

Now that would explain Eros coming after Aphrodite. But in this version Eros isnt even mentioned.

Now in the other versions, In the begining there was only chaos. Then out of the void appeared Erebus, the unknowable place where death dwells, and Night. All else was empty, silent, endless, darkness. Then somehow Love was born bringing a start of order. From Love came Light and Day. Once there was Light and Day, Gaea, the earth appeared.

or

In the beginning, Chaos, an amorphous, gaping void encompassing the entire universe, and surrounded by an unending stream of water ruled by the god Oceanus, was the domain of a goddess named Eurynome, which means “far-ruling” or “wide-wandering”. She was the Goddess of All Things, and desired to make order out of the Chaos. By coupling with a huge and powerful snake, Ophion, or as some legends say, coupling with the North Wind, she gave birth to Eros, god of Love, also known as Protagonus, the “firstborn”. http://funadvice.com/r/14k5hrevj0u

Basically love/eros came first. Which doesnt really match up with Eros being Aphrodite’s son. You’re thinking too hard. These are tales that were mostly told by word of mouth. I mean if you’ve got contradictions within the bible which was written down, you’re obviously going to have contradictions in stories that were mostly just passed down verbally.
