do i need passport to enter Turkey?
 

my husband and i are planning to go.

Yes

Well, where are you travelling from? As far as I know everyone who leaves their country of origin and wishes to enter a foreign land needs a passport - I don't think they let you through immigration/border posts even if you are travelling by train or car.
You certainly wont get far at an airport.

>As far as I know everyone who leaves their country of origin and wishes to enter a foreign land needs a passport
I don't need a passport to enter Turkey, my ID card will do :D

And can you get back into your home country - whatever that is - without a passport?

If you have an identity card from an EU country you can enter Turkey on that, and re-enter your home country. Otherwise you need a passport.
Note that if you are not a national of the country where you reside you cannot get an identity card from the country in which you reside. Not all EU countries issue ID cards.

>national of the country where you reside you cannot get an identity card from the country in which you reside

Of course you can! i.e. every German living in France can get a "carte de séjour" and travel to Turekey with it.
And you can even show this "carte de séjour" to enter Germany instead of a German id. (Got this knowledge from experience :D )

yes.

A carte de sejour is not the same as a national ID card for travel purposes. I cannot use my Vreemdelingspas as an ID card for international travel. Nor could a US citizen living in France use it instead of a passport. The passport free travel to Turkey covers only EU citizens.

>cannot use my Vreemdelingspas as an ID card for international travel
You should try to, it definitively works with a "carte de séjour" for a German, maybe your "Vreemdelingspas" shows your non EU nationality? That would be a problem. A French "carte de séjour" is just as good as german ID card for travel as a German.
