Can anybody explain why i lost the game?
The reason from game is resources, but we have the same amount of resources.

Perhaps you should submit a bug report. The official tiebreaker was originally based on how tall your landmarks are, but then got changed to how many resources you have, then got changed back to landmark height. I believe BGA has only ever had resources as the tiebreaker, so I can't make sense of it.

The game summary shows both players as “1st” (=it is a tie). But you lost ELO because you are the higher ranked player. That’s how the ELO algorithm works.
