Why do most men like grilling better than cooking in a kitchen?

I’m seriously curious! I think most food tastes better grilled and I prepare some marinated chicken ready to throw on the grill and my boyfriend steps in and wants to do it. I notice most men including him usually insist on cooking duties when it’s grilling. What is it? I asked him and he said, “I don’t know.” Articles say it’s the fire, meats, and sharp stuff and pretty primal. What do you think it is??
