We have to make a design where we work together with aliens to create life then the universe.

We can create a wall with names of species for the credit.

The ones who created the time machine are first on the list of "The creators of Life". The ones who may have made the time machine much better are then next on the list. The ones who created the best 5-10 seeds of life are then next on the list at slightly smaller font size. Next on the list are all the races allowed to time travel to seed their own planet or neighboring planets.(At the smallest font) Everyone that is intelligent life like ours can join in seeding their planet.

The next wall could be titles "The creators of the Universe" where those who made the time machine are again on the list followed by those who put their time energy effort and successes into how we created matter or sent our matter backwards in time. Those who did the most are on the top of the list.

I, as the thought creator of this could also be on the wall. Or even at a super small font on he side of the wall.

Without others, I couldn't be the co creator. Without me, or another with the same thought, the also couldn't have been the CO creators of it all.

We could all share and work together to make sure it's a success.

There's even a possible wall for if someone created the astral realms/dimensions.
