Time is a Measurement System, a Process for Learning and a very important Tool that helps us Plan and Predict. Though the Timing of Cycles, Rhythms and Development are essential for Life.
Try not to spend to much time thinking about Time, this is just one of many tools that we have.

The Universe was created about 13.7 Billion years ago. Was it the First time or Second Time?
Galaxies began forming some 400 million years after the Big Bang, or what ever happened?
Was Dark Matter Present then?  Was Dark Energy Present then?   Outer Space   Space
Is the Universe Expanding or is the Universe just Growing and Evolving?
Maybe the Big Bang is the reason why we are Flying through the universe? Maybe the Big Bang was needed to create motion, which is needed to create Energy and Gravity?

Is the Milky Way Galaxy the center of the Universe?    What is a Supercluster?   What is Light?

The Milky Way is a Barred Spiral Galaxy 100,000 light years in diameter containing 200–400 billion Stars and is about 13.2 billion years old with at least 50 billion Planets, 500 million of which could be located in the Habitable Zone of their parent star.
The Milky Way moving at a rate of 552 to 630 km per second, or 1,409,269 Mph.
The Sun is moving 486,000 miles per hour and takes 240 million years to complete one orbit.
The Earth takes one day to rotate and travels 67,000 miles per hour.
Earth orbits the Sun once every 366.26 times it rotates about its own axis,
which is equal to 365.26 Solar Days.   Action Physics

The most distant galaxy ever seen ' UDFj-39546284 ' is about 13.2 billion Light Years from Earth.
The galaxy dated back to a time just 480 million years after the big bang.

The number of Stars are estimated to be around is 300,000,000,000,000,000,000,000.
That is 300 Sextillion.   Vimeo    Galactic Center of Milky Way Rises over Texas Star Party

Timeline

Around 13.7 billion years ago it is believed that our Universe began.

After a couple billion years later Stars and Galaxies started to form.

After 9  billion years our Sun is formed around 4.7 Billion years ago.

4.5 Billion years ago our Earth is formed.

Around 3.5 billion years ago Microorganisms start to form on earth.

500 million years later or 3 billion years ago ocean organisms and primitive animals start to evolve.

2.6 billion years later or 400 million years ago we have Insects.

350 Millions years ago was the Cambrian Explosion.

250 Millions years ago was the Permian Extinction,
which caused Extinction of 95% of all living species? (Animals & Plants)

200 million years ago Mammals evolve.  Earths Early History

65 million years ago Dinosaurs go extinct.  Cretaceous Tertiary Extinction

600,000 years ago Homo Sapiens Evolved, or were Engineered or Created?

106 Billion Humans have lived from the beginning, and as of 2011 94% are Dead

What if there is Extraterrestrial Life? How will it change human life or how will it impact our world?
Maybe Extraterrestrial Life has already visited our earth? And the reason we don't have evidence is because they followed the Prime Directive. Could our world be the result Biogenesis?
Even if we did find another ExoPlanet like ours how could we even assume that life exists there?
The Drake Equation only assumes the possibility of life, it does not explain how life exists elsewhere.
Do you think that finding Extraterrestrial Life will somehow improve our world like some Magic Potion?
Technology can only do so much, unless of course Extraterrestrial Life can show us how to improve our dysfunctional inadequate education system. Then I believe we will see improvements. Till then I have more important things to think about, like how to improve education without having to depend on Extraterrestrial Life.   The Search for Life: The Drake Equation (Youtube)

Even if we did come in contact with other life form, there is no way of knowing what it would do to our lives? There is no way of Calculating this Probability, you can only guess.
And we all know what a Guess is?  So how can a guess Prepare you?

One Light Year is about 5.9 trillion miles.  (186,282 miles per second or  671 million Miles Per Hour)
A light-year is the distance that light travels in a vacuum in one Julian year (365.25 days)

Extinctions are like a Computer Rebooting, Life hitting the Restart Button.
 

If I can see the light, does that mean I'm connected to it's source?...

Our Sun, which is a Star, is about 96 million miles from earth (149.6 million km)
Solar System     Celestial Body
A Ray of Light from our Sun takes about 8.3 minutes to reach us.
The Sun is about 4.7 Billion years old and has about 5 Billion years left in its life.
Sun consists of Hydrogen (about 74% of its Mass, or 92% of its Volume),
Helium (about 24% of mass, 7% of volume), and trace quantities of other elements, including Iron, Nickel, Oxygen, Silicon, Sulfur, Magnesium, Carbon, Neon, Calcium, and Chromium.

Each second, more than 4 million tonnes of matter are converted into energy within the Sun's core.
The Suns surface temperature is 6,000 C  10,832 F

Diameter 1,392,000 km just over 109 times the diameter of the Earth
So that means that 1,300,000 Earths could fit in the Sun.

The Sun orbits the center of the Milky Way galaxy at a distance of approximately
24,000–26,000 light years from the galactic center.

The Sun is moving 486,000 miles per hour and takes 240 million years to complete one orbit.

The Sun rotates one complete turn every 34 days.

The earth takes one day to rotate and travels 67,000 miles per hour.

The Moon, earths natural satellite, orbits the Earth every 27.3 days
The Moon keeps nearly the same face turned towards the Earth at all times.
The moon is 238,857 miles from the Earth & has a diameter of 2,160 miles.
