When you look to define alive 

what comes up is not fixed 

While some say it’s a concoction

of chemicals starting to mix

Others say it’s a feeling

Which animals seem to lack

One you are able to lose 

through a virus or attack 

What makes you alive

Well science says they know

It is a set of reactions

with conditions you must hold

We can find the signs 

To tell us what's alive

But we can not explain it

For the answer’s not clearly defined

Life is only temporary

That’s a constantly stated fact

This world is indifferent

You won't be welcomed back

Because life is that cycle 

Always turning round 

Because what comes up

Must fall back down
