I have never programmed anything. I don’t know any programming languages, or 3D rendering software. I am a creative person who would like to make a game. Would this be a ridiculous idea for me if I were to buy UE4? Should I start elsewhere?
I would recommend you to start with a combination between a 3d program, the UE4 and some theory stuff (words that you need, how do games work,…). So start watching tutorials and try to create a simple game just with some basic meshes that you have made and basic blueprints setups.
“Learning by doing” that’s how I started game development and I have learned pretty much in those 1,5 years since I started
So yeah, I would recommend you to buy the engine (it will just cost you 20$ → because you can also cancle the subscription after you have bought it and you will be still able to use it) , download a 3d program (blender is a pretty good choice) and go into the game development adventure!
By the way, it would be good if you could post such stuff into the forum.

I say give it a try, as any other option will require you to do some sort of scripting at some level or another.
Coding experience is not required with UE4, but you will want to spend some time in their tutorials to find your way around the editor. You can build games using just blueprint logic, and UE4 has tons of sample blueprints and template projects available when you download the editor. I suggest going here to watch some video tutorials to get started.

Head to the last page, as most recent ones are a bit more advanced.
Hope that helps!
Having used two game engines prior and now this one, I can say that the blueprint system here will be easier to pick up than writing scripts. Now that said, blueprints still require great effort to understand and figure out how things work together.
If you were to start somewhere…honestly it’s all exceptionally difficult. Making a game in any engine is a gauntlet. The UE4 blueprints at least provide an easier entry point.
As far as being ridiculous goes, no way. No matter which engine you pick, if game development is an interest of yours then don’t let any lack of programming stop you. Everyone else in the business started with a severe lack of programming as well at some point 
Hey thanks you guys for positive feed back. So nice to hear the advice in a positive light.
