Here's what is incorrect about the question, "why doesn't god heal amputees". God does heal amputees. Look at certain types of lizards: they lose their tail, and, miraculously, it grows back. So, the proper question should be, "why doesn't god heal HUMAN amputees", since 'amputee' by itself is too general a term. Lizards are healed.
Time to get educated and change the video. Don't let your pride hold you back.
