Proof Of Physical Presence

[Solrac 0]

For the day of June,15 2012, If I have nothing to prove I was here. I do have an emailed receipt I could print from Amazon for the purchase of a game app on June,17 2012 just two days after. It shows my full name and address, do you guys think that would be enough to prove I was here on the 15th?

I actually sent something of a few days after but also of a few days before too.
