# Indentation of numbers in a numbered list

I have a numbered list in a LaTeX document and it automatically indents the numbers. How can I stop this from happening?

Typically one would go with enumitem on this, since it allows for localized (or global) changes to lists very easily.

\documentclass{article}
\usepackage{enumitem}
\setlist[enumerate,1]{leftmargin=*}
\begin{document}

\noindent
This is some paragraph text with no indent.

\begin{enumerate}
\item First item
\item Second item
\item Third item that is very long and should span at least two lines within this environment.
\item Last item
\end{enumerate}

\end{document}
