According to wikipedia and other reliable sources, The big foot was sighted in the suburbs of Philadelphia . People had seen it’s footprint but never captured the bigfoot itself . the closest people have got to a bigfoot is it’s footprint and nothing else. Many people jus claim to see it for popularity or fame but that’s all fake. to solve this dilemma i would usually set foot myself and look for this creature. Also places where i can’t reach i would advise the researches not to fall for fake evidence or anything but just find it out in the wild. On a personal account when i had visited himalayas certain areas use to say restricted.out of curiosity when i asked a local he claimed that those areas were restricted because there were weird noises and sightings which may be a problem mankind. I went inside and literally found nothing .
Many sightings are also based on the account of belief out of which some are true also.According to me the big foot exists and is just very illusive and is also scared
