Nit pick.
You actually can.
It's one of the defining characteristics of those pantheonic systems that its members, despite being Gods, were still flawed people with quirks, personalities, failings. Zeus is a womanizer, Hephaestus has a bad leg, Thor leaps before he looks, ect.
They were all, in the common sense of the word just people, who happen to have a lot of power. God of whatever was their day job. It came with responsibilities even. All those godly artifacts were personally crafted, some sucker has to wake up and literally drag the sun up in the morning or it doesn't raise, Hermes wasn't just the god of messengers, he was the messenger for the gods as well. If he takes a day off Artemis doesn't get her mail.
The "All knowing, all powerful, unknowable" God we get with the Abrahamic religions is the odd man out, even if they are very popular. Hell the Chinese have divine bureaucrats.
