Why do Zombies attack humans? To eat our brains!
The Zombies are after the NPC's that are on the other side of the door. They want to eat them so they are breaking down the doors to get to them. Make some Iron Golems to protect your villagers.
If the door is closed nothing can "walk through" the door.
zombies can break wooden doors down and pass though the opening.
If the door is open and the door itself is not in the way of of passing mobs then
anything but a spider can pass through the opening left by the open door.
here is something to try in real life
close your bedroom door and try "walking through" it. You cant physically "walk through" the door unless its open and out of the way. unless your a ghost of course.
No, only zombies can break down doors.
something called silverfish will be able to eat wood. now zombies can break down doors! And villagers can open doors. Now in 1.2, zombies can break through wooden doors, not iron doors. And if you are playing in a PvP minecraft server, an enemy faction(army) can overtake you territory and open your doors. Also if there are wooden pressure plates outside the door mob can stand on them and the door will open.
On hard mode, zombies can break wooden doors down. Endermen can move most materials too, which might mean monsters can enter your house.
No creepers can't destroy obsidian blocks but they can destroy a working portal.
Minecraft was not made by zombies. It was made by Swedish programmer Markus "Notch" Persson.
*Spoilers* The Big Doors only open during the last mission where the zombies break in. You have to gather the three parts to re shut the doors

Zombies are one of the first mobs, or mobile entities, in Minecraft. The zombie attacks you dealing damage depending on your difficulty setting and what armor you are wearing. Zombies also attack villagers and upon killing them, turn them into zombie villagers.(Zombie villagers can be healed when affected by weakness and fed a normal golden apple.) Zombies spawn in villages, dark areas, and when it is night. If an area is well lit a zombie cannot spawn unless its a siege in a village. The zombies will set on fire when exposed to daylight. On rare occasions zombies can pick up drop items and wield them as weapons or if it is armor or a head, as clothing. (Zombies do not set on fire by the sun if wearing head gear.) On normal difficulty or higher zombies can also break down wooden doors after repeated hits.
you get carrots in minecraft from baby zombies on chickens or spiders, you have to kill them and then you will get them.
Lots of stuff. Redstone powered lamps, zombies breaking down doors, AI for all mobs (makes mobs smarter), and many others
In Minecraft, zombies cannot break through glass on their own. They may try to attack you if they see you through the glass, but the glass will prevent them from physically breaking through.
