I have been playing Minecraft for a short time and I'm a beginner, so I set the game mode to peaceful. I would like to know if there are monsters anyway and if I go into a cave if I meet them there. I don't dare to go in because I'm afraid of hitting one, but actually I'm starting to need coal and other things. 😅
No there are none.
No, it does not exist. Do not worry.
You shouldn't get hungry in peaceful mode either.
I would still recommend that you set the mode to "simple" as soon as possible.
The whole monster can do almost nothing and if you don't want Creeper to break something you can issue "creature griefing". (However, villagers can't harvest fields and you can forget about automatic farms with them.)
No there's not but to be honest it is peaceful or just too easy. Once you have Full Iron you can practically no longer die and Full Iron You really fast. I would recommend playing on normal and as soon as possible to switch to difficult because even difficult is still very easy.
On Peaceful, you can only die from falling damage, fire, lava, or drowning.
Since you are a beginner, I think you are in command
/ gamerule keepInventory true
do not know It ensures that you don't lose the items from your inventory when you die. You have to enter the command in the chat.
On peaceful aka peaceful there are no monsters.
