Johannes manages to make a big sign just before the end.

The aliens find the mummified corpse and the big sign.

They puzzle over the meaning of the symbols and ask their best translator technician to decipher it.

After several days of searching through the database of their delta X optical supercomputer they finally understand the meaning.

That understanding raises a curious question; why did the individual scratch such a message in such a permanent way on such primitive material.

After a lot more research and searching through the area, they recover formed pieces of metal and other artefacts that are determined to be from a computing device that the individual probably owned and used.

Because of their extensive database from many inhabited worlds, they are able to figure out how these primitive machines worked.
By searching far and wide, they chance upon a complete mechanical unit that has been manufactured by the inhabitants of this planet. They study it and determine that it is a information storage device from one of these computing machines, and they are even able to transfer some information from this particular storage device into their system. Their system is programmed to translate what ever information is on the primitive storage media.

They are surprised when the translated information comes up with the message: Ihmisten olo tulee hyvin vaikeaksi täällä maan päällä sen takia kun he eivät kuuntele, työskentele, usko, taikka ymmärrä toisiaan.

They also find the universal mathematical formula e=(u/k)c, that surprises them even more because every planet where they have found civilisation with this knowledge, have also been able to traverse through their atmosphere and interplanetary space quite freely, yet this civilisation apparently had only very primitive devices for space exploration.

On the other hand; since there is no life anywhere else in the universe…………
