If there was life in outer space ,
If I lefts an ice cube under the sun,
If you wash your hands,
If Astronauts did not travel to space,
If spaceships did not travel to space,
If scientists find the vaccination the COVID 19 soon
It is used to see outer space
It melts quickly
People should save energy
People will be saved
Astronauts use them to travel to the space
People should use mask wherever they go
Scientists would not have enough information
We would not know the universe
They would be named Alliens
