if according to christianity the only way to god is through christ, what happened to all the native americans who lived here before white man came? [Spirituality & Religion]

I believe in God and Jesus but find it hard to believe every that doesnt burns in hell. Because if that was true that means all those people who lived before white people were here are being tortured for all eternity only because they were born somewhere that had never heard of christ before. Same with women in saudi arabia even today. Any religion other than islam is illegal n women arent even allowed out of there house without a male escort. Why would she burn in hell because she never risked her freedom to escape, learn and convert to christianity
