WIN BIG SBD PRIZE ($$$)

Hi steemians, I would like to remind you that the big treasure hunter on steemit launched by Hive account@jacksartori is opens. It will be your task to find the treasure with the chance to win a huge cash prize ($$$). This treasure hunt will be developed in six parts, each part will consist of a post with the relevant clue. Only the first people that solves the last riddle will win the prize.
The posts will be published once every three days

• Monday 7 May
• Thursday 10 May
• Sunday 13 May
• Wednesday 16 May
• Saturday 19 May
• Tuesday 22 May

The answers can be written as a comment under each post except for the last one, which must be sent to Hive account@jacksartori privately.
Here you are the first clue:

It's the first one that comes and the last one that goes.
Seeing can not and can not even hear
you can not smell or even hear.
It is at the bottom of the ocean and behind the stars
And every space he fills.
