What if we are the replicated life sent out to colonise the universe. It would be hard to self-replicate knowledge and especially knowledge of our own origins over such distances and tiny cracks.

I am also not too sure the maths adds up either.
Lets assume that this "spread everywhere" civilisation does exist, and it fortuitously started evolving just after the Big Bang, and neatly at the "centre" of the universe (i.e. somewhere that is not next door to us, nor the furthest point possible from us)
Lets also assume it took them roughly 4Bn years to evolve to the Promethean level (age of the Earth) and so have been spreading for past 10 BN years.
And (yet) another assumption - they spread uniformly outwards, travelling at speed of light (!) but taking a recharge period to, I don't know, consume the resources of a planet, build a few houses, before spreading again.
So, with a observable bubble of 46 bn light years, and 10^^23 stars in it, I think the following calculation works
* there are 10^^23 stars [1], spread evenly over 46 bn light year diameter bubble
* they atarted their migration to us (to everywhere really) 10bn years ago
* between the "them" and us there should therefore be a even distribution over 23 bn light years or ~ 10^^23 - 10^^9 = 10^^14 stars.
* given a "pause" of 100 years at each star system and light speed travel in between that is still 23 bn years plus (100 x 10^^14) 10^^16 years or a ridiculous number that I have probably got wrong but is clearly older than the age of the universe many times over.
I know this can be tweaked any which way, but if we are looking at the pan-dispersal approach, even simple lower bound cases make it highly unlikely that a civilisation spreading enormously fast and comprehensicvely throughout the universe will still "never" get here for any value of "never"
