Nothing existed before we came around. To notice.

They were there, alright. But didn’t existed, yet.

Most dictionaries do not discriminate between ‘being’ and ‘existing’.
But I still recall, vividly, those moments when – as a teenager, I tried to make myself remarked by the girl I fancied at that moment. More often than I’d like to remember, it was as if I didn’t existed at all.
I was standing there, making a fool of myself, yet I didn’t existed at all.

Simply because I wasn’t noticed.
By the significant one.
