That's like asking you why you need Jesus, or Allah, or whatever your religion is. Their myths were their science. That was how they explained the world. The seasons were caused by Demeter missing her Daughter, Persephone when she went to the Underworld. Storms were caused by Zeus being in a foul mood. etc.
You need not contact anyone, the worship of gods and goddesses no matter their origins is a personal choice.
As is the case with all gods, they are real to the people who worship them. To the ancient Greeks, their gods and goddesses were just as real as the Abrahamic God is to modern Christians, Muslims and Jews. They worshiped and prayed to the gods whenever the need arose. They believed that if they offended any of the gods, then disaster would befall them. In the scientific sense, gods and goddesses may not be real, but faith made them so in terms of their effect on people's lives.No, the Greek gods and goddesses are not real. In the ancient times, the Grecian people did not know the reason behind simple events, such as thunderstorms. As a result of this, they made up the gods and goddesses to give meanings to various events, not only thunderstorms, but also drought, famine, and death. It is said that creating these myths gave the people a sense of comfort and knowledge because it showed that everything had a cause that was logical to the Greek mind.
I love Greek gods! Anyway, No. There are gods/goddesses (Geras- god of old age, Ate- goddess of foolish acts, Mania- goddess of insanity, and Dionysus- god of partying and drinking, to name a few) that are just kinda there and never fight battles or rescue people.
In order to be naked, they would first have to have bodies. When they did, they were invariably clothed, because there are stories in which they make a point of noting that the god or goddess was disrobed. You wouldn't need to make that distinction unless the figure was normally clothed. Look at it this way - the Greeks gods were just an extension of the Greeks themselves. And contrary to common belief, the Greeks didn't run around naked.
They are a part of the world's historic religions.
There's greek othodox church, so there was a lot of greek priests.
The Egyptian's religion and gods and goddesses was their answering way at looking at life and the why and how of the world they saw around them.
There are, literally, hundreds of Greek gods and goddesses. The main ones are Zeus's wife, Hera, along with Athena (goddess of wisdom), Aphrodite (goddess of love), Persephone (goddess of the underworld), and many more.
This is an interesting question, because while the gods and goddesses were generally regarded as omnipotent, there was a definite "fastest" among them, and it was Hermes. Second to him would have been Iris. They were the messengers of the gods, and were expected to be expedient. Hermes was also the god of travelers and thieves, both of which imply a need to be hasty.
The god of the sea was Poseidon. If you need a goddess it would be his wife, Amphitrite.
To learn about Poseidon (and the other gods and goddesses too) read all the Percy Jackson series by Rick Riordan. Everything you need to know about all the gods and goddesses including Poseidon in these books!!!!
They respected their deities and did their best to please them. But, the interesting thing is that their stories often showed that their gods and goddesses were flawed, just like mortal men. The tale of the Trojan War, specifically, highlights the need to not only honor the gods, but to offer recompense for past wrongs, even if they were committed by your ancestors (e.g. Poseidon killed Lacoon for trying to warn the Trojans about the Horse because Priam's father had insulted him). But most importantly, it showed the Greeks that their gods were ever-present in their lives, and that while they were all powerful, men were still expected to do for themselves.
