There will be no life to start with, just a climate hospitable for life.  It will take Slough's emergence and presence on a planet to get life started.  Whatever things Vestec has created to move within the depths of space cannot be classified as true life, instead being autonomous, physical pockets of chaos.

It makes me really think of Bayonetta, actually.  In that game series, the angels are vile and twisted eldritch creatures in shells of flawless gold and marble, in essence things purely organic.  Demons, meanwhile, are vile and twisted creature-like machines of diabolic, hateful metal.  'Life' created by Toun or Vestec, for instance, without Slough's help, will probably take extreme forms such as these.

The kind of natural life that will colonize and thrive on planets will come ultimately from Slough, though other gods can disseminate it once it exists, which it will after the Big Bang has created a universe hospitable for it.

So, if I understand you correctly, the Big Bang will create planets with the [i]potential[/i] for life to develop and the right [i]conditions[/i], but no actual life yet. I.e. there would be oxygen, atmosphere, seas, volcanoes et al. but no living creatures of any kind, from the smallest germ to the largest whale/mammoth.
Does Slough not wish to add these things, correct the 'lifeless' things the others have planned for?
