Why can bedrock be destroyed?

A (loops)

Hey have tried the DOS edition of Minecraft? https://github.com/john314thegeekygenius/Minecraft3D-MS-DOS (you must download RetroArch so you can play the DOS game)

At first you can't see me...BUT THEN when I delete the bedrock YOU SEE ME BECAUSE I WAS BEHIND THE BEDROCK THE HOLE TIME

Why is the stone have the same texture as the water block but just different colors [there might be some copy-n-pastin ya'll]

I hate my life, I just want kill myself
