First time doesn\'t matter, just like minecraft, this is an alternate universe so future, past, present not really important.
Second, water is required for carbon based lifeforms to exist, so, need to figure out a way to produce it and use it.
Third, again oxygen is required also.
Fourth, nourisment is also kind of a thing.
So, how in space do you produce all this, well, obviously through some kind of matter transformer. Do you need to kill an animal of some sort to get protein, no you can harvest proteins from grasses or trees or any living matter, water can be squeezed out of anything and of course there are ice planets, ice is of course water so factory processing of ice to create water, water is of course H2O, so once ice is processed it can be processed again to create oxygen and the byproduct is hydrogen which could then be used as a fuel for energy production.
You put it all together and you have protein based food, processed water and oxygen with hydrogen to power ships and all the other gadgets yet to come.
