Also I heard in a video review that the mobs or even bosses can attack your house and destroy it, some people even rage quit and stop playing when a mob kills their base they spent 20-50 hours building. I'm REALLY not into this. I hate losing everything I earned/made/archieved. So screw this.

I've never lost any building due to a mob raid.
A lot of players like to discuss about building defenses and all manner of ways to protect the architecture they have lavished their time on.
None of this is necessary though.
Raids are a mechanic the dev's included to encourage players to keep moving and explore. There is a time threshold for staying within the vicinity of your buildings and when that elapses, a raid will be triggered.
However, the thing you have to keep in mind is that raids target you. It is only when and if you are inaccessible that mobs will turn their aggression on structures you have built.
Therefore, the best way to deal with a raid is not to hunker down and rely on a defensive strategy, but rather to get out and in to the open and slaughter them. This is entirely possible ;)
So... worry not.
The game actively encourages you to explore and work towards completing the mission Odin set for you... namely to kill the bosses and eventually beat the game. There will be a game ending, it just hasn't been implemented yet.
Now, you do need somewhere to rest up, collect resources and craft better foods and better gears, but that doesn't mean you are required to build elaborate bases. You may of course, but it isn't mandatory and it certainly is not at risk of mob destruction ;)
