Does Jen believe in Bigfoot?
I think she would say that she finds it unlikely that there’s any large species of ape or the like roaming North America that we haven’t found any evidence of yet. There would have to be a fair few of them in order to breed, so you’d expect to have found some remains or droppings or some sign of their activity by now. Unless the bigfoot reported years ago was actually the last of its kind, in which case it sadly most probably is dead by now.
Of course, Bigfoot may not be a mere ape and is actually fueled by forces unknown to modern science. As a science type, Jen would actually be pitiably thrilled at the discovery of such forces, as she would just by the discovery of Bigfoot itself, but as of now there’s no evidence for them.
Now, the Yeti on the other hand…
