I will explain why.
Fate/stay night has 3 routes.

1. Fate
2. Unlimited Blade Works (UBW)
3. Heaven's Feel (HF)

In the original visual LN, you can go through these 3 routes. Their beginning point is same but they are not related the slightest to each other. You can consider the as 3 different realities that happened after the beginning point.
Ufotable made a very good adaptations of the UBW and HF route but they did not create any anime for Fate route. Studio Deen's Fate/stay night is a bad adaptation because it combines all these routes together.

Now what you have to watch is
https://anilist.co/anime/10087/FateZero/
This is a prequel to all the routes of Fate/stay night and happened 10 years before the beginning point I was talking about earlier. The whole Fate/Zero story is common to all the three routes and is meant to be seen after you have gone through these 3 routes.

Then you can watch all the other spin offs if you want to. Go here if you want to know more.

PS: I have saved all this case so I don't have to type this again and again.
