What proves the existence

I questioned today to the sky,

What proved my existence, 

Through the massive thunder

It spluttered & Roared, 

"Your name"

I questioned the blue sea,

 What proved my existence? 

The blue waves answered 

While splashing the rocks,

 "Your deeds"

I questioned the earth,

What proved my existence, 

They replied with a mushy fragrance, 

"The moments you spent"

I questioned the wind,

What proved my existence,

They blew the little strands of my hair,

 And answered, 

"the people you care"

But

I questioned myself will this prove my existence?

What if everything failed,

what if the name I hold isn't mine? 

what if the deeds I do are turned unknowingly?

What if the moments I spent are just an illusion of my brain?

What if the people I care about are manipulated to forget?

What if nothing prevails to say I was alive? 

Would my existence be hampered?

 Would I be the unseen soul in a distorting world?

 Or would I be a figment of someone's imagination

All settles to a question, 

"What proves the existence?"
