Hello @Aaron1450
Unfortunately this is a right of passage on Airbnb and we have all been through this and you're correct in assuming that this is very likely coming from a scammer who may very well ask you to contact them off platform or even ask you to send them a video in the next message.
As a newbie, accepting a long term reservation is not the best way to start as you need to get as many excellent reviews as quickly as possible to appear in guest searches. You could limit your max stay count to stop these long term stays until you are established? Winter months = potentially heavy heating bills according to where you are. Look in the Host Guides section for the pros and cons of accepting long term stays on Airbnb Aaron.
The only way to know if a person is genuine is to communicate with them and ask them enough questions so that you feel comfortable accepting their reservation. This came through as an enquiry so you don't have to do anything but reply to them asap and you have done your job. If you want to learn more about the difference between an enquiry and a trip request and the actions required, read the Host guide below:

You are able to flag any guests who violate Airbnb's policies by clicking on the three dots in the message dialogue or by using the flag symbol to alert Airbnb.
Good luck!
