is this omega fake or not?

Whatever you found online, it probably wont be accurate for a recent watch like that so don't bank on the 2008 date. That said, the box and book set does look older than 2017. Are there warranty cards with it? You can also get a rough date from the version number on the spine of the instructions book, but of course those items might have been added later. If he has the cards, show those as they are harder to fake or add convincingly, perhaps those are dated 2017. From those pics at least, nothing looks amiss. The deployant clasp is an earlier design by the way, in the past decade they have been more angular, that's the earlier more rounded design again suggesting it could have sat for a while before sale. Or was added to replace a missing bracelet. The PIC code on the cards (if present) would tell you if this is the case.

Well its one of many Speedmaster branded watches, some sell for much more than others. Be careful that you are comparing like for like when you cross shop this. This is a 7750 based model and they are usually priced somewhere between the compound movement Reduced models and full fat 1861/3861 movement Pro models. I don't know that model intimately but I suspect it is an OK rather than a wonderful price. Especially since it is not a full set with no recent history of a service. If the seller provided the PIC code for the model, maybe take a look at eBay for sold listings of similar.

After a quick look, it might be this, maybe use the details here to search on comparisons:
