The first blog should always be

an elucidation of the reasoning behind the choice of title for the blog, a justification: An, the personification of heaven in Sumerian or rather Akkadian religion/mythology was worshiped for a few millenia before his reign ended by the onset of more specialized regional gods who, I presume, gave hope to people struggling in these particular areas who would feel daunted praying to a single god who specializes in everything. Perhaps the thought of one god never entered their minds. Perhaps this first thought came when the ruler of the gods killed all the others or became so powerful that the others had no dominion over the fates of those praying: they could not trust the lesser gods to cure their problems as, they believed, they would have to ask Marduk to help them help us. I will struggle with this question for a decade, no need to kill myself attempting to defeat it here.

As the reincarnation of An:

How can a deity be a person, if it is a personification?

What do we know about heaven? All we can believe about heaven is whatever we think it is in our dreams but it may just be better than even this, better even that euphoria:

Higher than high
lift the tallest building right into the sky
Better than bliss
More perfect than the day you had your first kiss
That vision you had, in your dream
would have been bad if you were used to the euphoric gleam
radiant and effervescent, translucent and so clear
you wish it were you, you wish you were me:
An, The personification of heaven, thus all you hold dear
decadence, harmony, peace and beauty.
