The vast majority of eight year old probably do not have "sexual fantasies".
However this does not mean that children are completely oblivious to sexuality. Most won't know in any firm sense what sex is about, but kids, especially young ones are quite aware of their bodies, and not terribly shamed to express their curiosity over those funky parts of anatomy or to ask about the gender roles they see expressed in day to day interactions between people.
Sexuality is a very basic biological thing, and is present before puberty. Just not to the extent of a 8 year old trying to screw her teacher. Unless, someone close to her is modeling such behavior for her to copy- an older sibling or parent who is a shameless flirt. Without that, an 8 year old acting that way is highly implausible.
