Well, there's lots of advice on this thread and I'm guessing that's precisely why you posted your thread!
However...
Everyone's opinions are what THEY would do in your position. Which is based on what kind of photography THEY do and what kind of photographer THEY have developed into.
Without wanting to be patronising, YOU need to develop into becoming YOU as a photographer. YOU might find you get more use out of the 35mm, then again YOU might find you get more use out of the 50mm. It depends what you find you like shooting and your personal style. And sometimes it just comes down to which lens YOU click with.
Sorry for all the caps, but it's to highlight that we can all give you all the advice under the sun but ultimately it's based on what WE would do! Photography is about what excites you, what makes you want to press the shutter release, what gets you back out there on a wet, cloudy day. If that's the kind of things you'll want to grab the 50mm for, then get that. If it's the 35mm then you should prioritise that.
However, having said all that, there's some good general advice - you'll almost certainly end up getting both. Or equivalents. My first lens was the 50mm and I'm just waiting for delivery of my 35mm. I love primes, but then I love my DA* zoom as well. LBA is a problem!
What you have - which I didn't - is your zoom which covers both focal lengths. This is a real bonus. I'd suggest spending a week or so (depends on how many photos you take - ideally you want to be doing approx 500 photos in each of these scenarios...) with your zoom taped to 35mm and another period with it taped to 50mm. See which "tickles your fancy" more. If you find yourself hating the 50mm and wanting to untape your zoom, then you know your answer. And vice versa.
What I love about the primes is that it makes you think about photography more. Don't get me wrong, my DA* 50-135 is my go to lens a lot of the time, because I can be a bit lazy with it and it does produce some wonderful shots. But I find I'm much more careful with a prime and I end up with a higher % of keepers because of it. It's great discipline. And the reason I started off with one. But trust me, you'll end up with both so it's really a question of priority rather than "which"...
By the way, I'm pretty much a complete beginner as well... so I've been through this myself recently. Just in case it's of interest, I posted this about my journey so far:

Without wishing to patronise again, both lenses will deliver far better images than you're capable of (or I am) at this stage of your photography. They're sharp, consistent, reasonably fast but also easy to use. You're not going to be limited by either.
