The US Goverment is getting a loan that amounts into the trillions because of the ressission! where does all that money come from ???

Have the just plucked it out of the air and added the zero's to their bank account. Who do they pay it back to?
If some bank has had to make more money to give them, does that devalue the money me and you have because theres more money about ???

If anyone can explain it, please do so. :~:
