Should Minecraft really be from 6 years old?

Everyone knows Minecraft. The ultimate and most famous game of all time. But if you think about what you do there in the game you will question something. Here are examples:

Mobs (evil), check out the creeper, it looks creepy and it explodes. Zombies, anyone would get scared of such creatures. If you think about what they look like in real life.

Eating if you have played Minecraft for a long time and know that you can use the lighter to light animals and then kill them to get fried meat? (Could imagine that the green ones are on my door)

Isn't that brutal? And think about what else there's. Also think twice!

There's nothing brutal or anything like that

Why should Minecraft be 12 and over? You don't see blood, the graphics are child-friendly and there's no goal to do anything that is not child-friendly.

I will remember!

Thank you. Could you give me a "thank you"? For my profile.

Klaro, for such a good answer I'll even give you a * most helpful answer *

Wuhu.

I would be happy if you continue to give such great answers!

I give my best.

Even Terraria is brutal and creepy compared to Minecraft. And Terraria is neither brutal nor creepy

The game is from 6 but it doesn't contain anything brutal except for killing monsters and animals. From my point of view it should be from 0 and it can't play for 3 years anyway.

You can also learn a lot through Minecraft. And the following:

Circuits / Power (Redstone)
Math (e.g. The coordinate system)
Geography (cartography)
Programming with command blocks.

and much more. TheJoCraft has uploaded a detailed video:
