is there a debit card that earns miles (1 mile per $1 spent) and doesn't have an annual fee?

i don't know of any that are comparable to credit cards. there's a reason for that. debit cards, being newer, have a much lower interchange rate. since collecting on debt is risky and less predictable, rewards / miles are paid from those interchange fees. this means with a debit card there's less money to pay you with. so what can you do? assuming your credit isn't terrible, you can just open a credit card account and pay in full for purchases by the grace period. i don't know how all cards work, but my grace period allows me to pay in full by the billing date (roughly a month from purchase) and incur no finance charges. in effect, i get a small 30 day loan with no interest, and a cash back incentive (i dislike miles). you're also less liable for fraud via cc than debit.
