You should not put an aluminum container directly in the oven

If you put an aluminum container, containing food to be cooked or reheated, in your oven directly on the shelf, the shiny base will reflect a large part of the oven heat (like a mirror). This means that the food will take much longer to cook or heat through than usual.

How to seal a terrine or casserole dish

The French have a term for it: "luter", which means to seal around the lid of a cooking dish with dough.

What other kinds of pans can be used to reheat food or cook with other than Aluminium? Concerned about ingesting Aluminium and seeping into food. Use aluminum to make turkey, roasts etc. Also use aluminum pans to reheat food constantly.

Absolutely.

Would you still be able to if you don't have a sheet pan

Of course not, oven don't use light to cook/heat, who say that?
But the heat they produce, mostly infra-red, act as light in front of a shiny base of aluminium.
So this is true, sorry for you...

Uhhh, this is completely wrong... this is not how ovens work. "the shiny base will reflect a large part of the oven heat (like a mirror)" Ovens do not use LIGHT to heat food, rather convective heat transfer. A shiny surface will literally have no impact on how your food heats.
