The universe will eventually collapse back into a singularity.
The universe began as a singularity approximately 13.8 billion years ago and has been expanding ever since.
The universe has always existed in its current form.
The universe was created simultaneously with Earth.

It supports the Steady State Theory of the universe.
It's the gravitational waves from galaxy formations.
It is the thermal remnant radiation from the Big Bang, acting as strong evidence for the theory.
It's the light emitted from newly formed stars.
Light elements were formed by exploding stars.
Light elements always existed in space.
Light elements were formed during stellar nucleosynthesis.
In the first few minutes after the Big Bang, conditions allowed for nuclear reactions that formed light elements like hydrogen, helium, and lithium.
