That's fine. 4 hours isn't enough to really get into the meat of the game yet. If you feel like you're kinda stumbling around a bit without quite knowing what the goal of the game is, that's normal. The game is specifically designed to not give you any objectives, and a big part of making the game enjoyable is to not try to judge the game by regular game design conventions. There are no win conditions, no lose conditions, no objectives, and the game becomes much more enjoyable if you just play the game in the way that you think makes the most sense. You'll just need to have a bit of faith that there is actually an end, you just never get told how to get to the end.

If you're struggling with not crashing, then that's a different issue altogether, and honestly my advice is to just use autopilot. Make sure to disable autopilot if you start to see that autopilot is going to crash you into the sun.

I get it might not be for everyone. Until the main thing happened the first time I wasn't sold either, but personally, the game does an amazing job at making me naturally and fervently curious about what the heck was going on

What part don't you get? If you can be more specific, people might be able to help you out with some largely spoiler-free hints.

For example, do you not get 'what the goal is' (this is a legitimate concern, and someone might be able to give you a direction to pursue for example)

You’re basically dropped into a huge set of mysteries.

You get to explore, at your leisure, anything you want.

There’s places and dialog and written records that contain clues and references to different threads of those interconnected mysteries.

As you play, read, explore you uncover more and more and what happened, is happening, and will happen start to make sense and you build a picture in your mind of what’s going on.

There’s no unlocks or progress except for these moments of discovery. And as you learn and discover more you can get access to new places to dig into the mystery because you have acquired the knowledge that lets you do it.

Don’t feel bad if you don’t click with it. I love puzzle oriented games and while this was the most unique experience ever in a game (and I suggest all people try it), it was really a mental challenge getting through this game. I actually abandoned the DLC, because I honestly reached my limit. You have to really love repetition.

I'm talking about that one
