In the beginning was a discarded mobile phone. In its memory were a list of phone numbers that its former user had typed into it, and a couple of SMS messages they'd not got around to deleting. There was also a list of recently dialled numbers, plus various odds and sods like volume settings and so forth.
There was also a sense of purpose, though not one with anyone you might call awareness or intelligence behind it. At first it was very vague, but as time passed and no-one called the phone it grew to a burning intensity.
What kind of purpose derives from an address book and a left-over SMS? Normally none at all, of course. But in this case it was a strange purpose indeed, nothing less grandiose than the creation of the universe itself.
Since the Phone had no internal clock, and had long since run its batteries down so much that it could no longer send or receive radio signals, there was no way it could know that the time of the universe's creation was far, far in the past. But this proved of little consequence; for the first thing the Phone created was time itself.
Now there was just time and the void. So the Phone created the stars, and the planets, and towns and cities, and animals and plants, and people. Time passed, religions rose and fell, none guessing at the strange origin of their universe. Eventually people on one world started to construct mobile phones themselves, and ultimately they created the Phone itself, and thus was the universe born.
