Hi Etart,
Welcome to this Microsoft Project newsgroup
If you go to Tools/Options.../View tab, at the bottom you will have the
option of showing a project summary task. Its start will be driven by the
start of the first task and finish will be the end of the last task. So, if
you now enter a start milestone at the beginning, then the project summary
will start at the same date. You cannot put a milestone before the start of
a project, as the milestone itself would be start of the project.

Hope this helps - please let us know how you get on
