HTTP ERROR 500: When I attempt to upload a Laravel project onto my remote server

I am a bit of a beginner in Laravel and remote servers, etc, so please bear with me if I am asking something super obvious or simple.

I wanted to create a Laravel project on my webpage, so I connected to my server via Putty, and directly put the command through the command line of Putty. It created one (blog was its name) successfully, but it created the project inside of my webpage directory inside of its own folder called blog. I moved all the files and folders inside of blog to my main webpage directory through FileZilla. I did not change the Laravel code at all, it should show just the default start up page. When I visit my webpage, it throws an error like: HTTP ERROR 500. Just for curiosity, I visited my webpage/public (I know I do not have any route defined like this) and it threw a Laravel error like: NotFoundHttpException in RouteCollection.php line 161.

I want to upload an image so I also posted this question on stackoverflow, if you would like to have a look: http://stackoverflow.com/questions/43070849/laravel-on-my-remote-server-isnt-routing-properly

Any help on resolving this issue would be of great help, thank you for your help.
