Move away from the convergence zone. It might not be a great place for a main base if you want peace and quiet. Fun spot for a mini base though with defenses noted below. But since you are pre stone tech maybe just keep it on the back burner for now.

When you are ready for all that action then consider digging both a trench and inside the trench build an earthen wall fairly high, higher than the blobs can hop. Otherwise you will get no rest and the fun starts when you get drake events, well actually it will be good pickins after they kill all the locals.
