Somehow I accidentally lost all my original photos from a folder on my computer. I can see them in lightroom bit lightroom cannot find them because they are gone. Is there any way to take what is being shown in lightroom and export or save them somehow? I tried export and it won;t work without the original. Any help would be awesome.
Did you check the Recycle Bin?
If they are not there, you might want to try downloading and installing and running something called an "undelete utility", which can — in certain situations — restore "deleted" files. There are freeware undelete utlity programs available.
Now would be a good time for you to begin planning your backup strategy, so you never lose photos again.
