Big Bang Theory Events?

Question

I cannot figure find information on how to put these events in order. Can you all help me put these in orfer from the earliest to most recent?

Here are the events:

1. Formation of Galaxies

2. Cosmic Background Radiation Freed

3. Planetary Nebula

4. Nucleosynthesis

5. Quarks Combine to make neutrons and protons

Answer 1

Brant is more or less correct - except...

Nucleosynthesis did happen in the big bang - but it happened after that too and continues to happen - so it should go

5, 4, 2, 1, 4, 3, 4,

or something like that...

Answer 2

5, 4, 2, 1, 3

but that would be if you meant big bang nucleosysnthesis,  that also occurs when stars go nova.

Answer 3

5,4,2,1,3
