It seems fairly common for Christians to refer to Adam and Eve has being husband and wife. In particular, when (in my experience, evangelical) Christians are discussing questions of sex and marriage, using Adam and Eve as the pattern for creation, they treat the relationship between Adam and Eve as identical to that of our modern understanding of marriage.

One argument against this is that, from what I am aware, Genesis doesn't refer to them using words like "husband", "wife", or "marriage". In the UK, it's becoming increasingly common for couples to live together and start families with actually be married, and a sceptical person may attempt to attribute a similar arrangement to Adam and Eve.

What is the biblical basis for believing Adam and Eve were actually married?

I'm largely interested in answer from an Evangelical perspective, but would accept answer from any denomination in which this is a common belief
