i dont get it

i dont get vegans/vegetarians. people have canines cause were designed to eat meat. also if we werent, then why did every ancient culture kill animals to feed themselves? if they could have survived on grains and berries they would have, because hunting was not always rewarding or safe. also i dont get evolution deniers (i cant spell that). seriously there is evidence of evolution. sure, god could have created life (which i believe) but he didnt create it as we know today, he probably just provided the means or jus watched his creations grow.
