Each year almost 4 million babies are born in the US. Although thinking of 4 million unique names is pretty difficult, theoretically it is not impossible. Nonetheless, there are always many babies given the same name. For example, in 2013 more than 18,000 boys were named Noah and more than 21,000 girls named Sophia, the most popular boy and girl name of that year.
