Feeling the warm glow from anything hot on your skin is evidence of infrared light being emitted by the hot object or gaseous flame.
A marshmallow over a bonfire is a radiant heat transfer. The marshmallows are not in direct contact with the flame but are held very close to reduce burning.
When you stand in front of a bonfire, you feel hot because the fire emits infrared radiation, which directly heats your body. Additionally, the heat generated by the fire warms the surrounding air, creating convective heat transfer. Together, these factors contribute to the sensation of feeling hot.
Yes, whereas convection heat transfer is the transfer of heat via a liquid, and radiative heat transfer occurs through empty space (like the heat you feel from the sun).
Radiant heat transfer is the primary way you feel heat from a campfire. There would also be convective and conductive heat transfer to the air.

It's primarily radiation.

As heat radiations fall on the body, we feel hot.

Condution
This type of heat transfer is called conduction. The transfer is from the warm hand to cool water.
When you dip your hand in cold water you feel it cold. Can you name the mode of heat transfer and its direction?
The answer is heat transfer :D
