EDIT: adding my sources for these stats up here. (I posted a comment with them but it seems like a lot of people aren't seeing it.)
40% of American adults believe in young-earth creationism
77% of American adults believe angels are real - kind of an old source (2011) but I don't get the feeling that the number has dropped a whole lot since then
EDIT2: I found a more recent figure for belief in angels: 72% as of 2016. Thanks @T_Doug
77% is probably an older figure from when America was more religious
edit: wait, it says "A majority of non-Christians think angels exist" so I might be back to thinking the study fucked up or is being presented in a misleading way or something. Like, people took "angels" in a metaphorical sense or something.
Yeah, very strange.
