let’s say i have a huuuge family, let’s say i have my brother, who of course he’s family, then i have my mom and my dad, which are family too. then i have my grandma and granpa, they’re family too of course!! but then my grandma and grandpa have like 4 or 5 siblings, and those siblings have children, are those children part of my family or not?? let’s say those children have other children, are these still part of my family?? if you say yes then that means humanity is closely related and we’re all siblings, and if you say no, you are saying that my family is only mom, dad, brother, and grandparents… please help me figure this out, this could actually help us figure out the beginning of the universe & humanity itself!!!
