How do I combine meshes?

I’m new to Blender (and 3D modeling) and I’m starting simple with a snowman project. Seems simple enough especially since I prefer to learn through trial and error and looking up what I can’t figure out

unfortunately even looking it up I can’t figure out how to attach the two spheres that compose the main body of my snowman, and while I want to eventually have it possible to move them seperatly for animation currently this prevents me from moving around the model without having to be very careful while alligning them

So how do I attach 2 objects?

Select both then press CTRL-J

press ctrl+shift+tab then choose second (vertex)

in edit mode press control+ shift + tab the choose second one option and move meshes together
