with debit you take out your own money from the bank and with credit you use the government's money and have to pay it back. The more you use your credit card the better the credit score and if you dont pay back in time your credit score goes down. Without good credit you can get a house and I believe some jobs.
A debit card is an account to which the users money comes directly from the persons checking account. A credit card is when the purchase is charged to a line of credit, and is paid for later.
