You are extremely ignorant.
There are many parts of the US that have legislated away all sex education other than abstinence, despite it having the obvious effect on teen pregnancy (and therefore abortion rates where it is legal!)
There are tens of millions of fundamentalists "christians" in the US.
"I haven't personally seen it so it can't be real" is absolutely a wild take in a place as heterogenous as the US, with 350 million human beings, huge diversity in backgrounds.
Have you even stepped foot in a random Christian church? Or "Christian" church? They are utterly insane, and will have a hundred loyal adherents even in rural towns.
The "christian" cults that were common around northern maine included one that banned Halloween and reading harry potter.
There is, right now in the US, a stupid cult of "Catholics" that insist the church's official policy stances after about 1970 were blasphemy, and that they want to go back to pre Vatican-II policy, which includes such gems as Jewish people as a whole being officially labeled at fault for the crucifixion of Jesus
The US has, in it's history, cultivated up to SIX "Great Awakenings", which were events in US past where millions of dumbasses just started following whoever showed up to give speeches in the park, where multiple modern "Christian" religions spawned, including Mormonism and "Christian Scientists" which were literally a harem of morons who fell over themselves trying to please an insane woman who made up stories of former illness so she could claim she was "Healed". Her lies were mostly stolen from a quack practicing Animal Magnetism.
Go look up Ken Ham and the Answers in Genesis folks. Their absurd Noah's Ark gets a million visitors a year.
Insane fundamentalist christians in the US are so big and powerful that they run an entire parallel economy for all their grifty grievance propaganda, where you can buy shoddily produced ripoffs of popular teen movies that have all the writing removed and replaced with "The government wants to murder us for believing in god", because it's essential they keep their kids indoctrinated in a belief that they are forever victims, so they can justify their absurd acts like voting in a literal pedophile just so they get supreme court justices who will overturn Roe V Wade, and as they show with their refusal to actually educate teens about sex and it's risks, they do not care about reducing abortion or unwanted pregnancies, and instead simply want "Sluts" to be made to suffer, which should be the complete opposite of what Jesus Christ would do, as Jesus made a big show of accepting the literal untouchable class of people like a prostitute and lepers.
About 35% of Americans, 100 million people, will state directly that they believe the earth is less than 10k years old. They explicitly believe that God created us as we exactly are now, that evolution is impossible, and therefore that all of science is in a gigantic conspiracy to mislead you, and therefore all of science must be an agent of Satan himself.
The other two options in this poll were "Humans have evolved over millions of years, but god was involved in this process" and "Humans have evolved over millions of years, but God is not involved".
