Someone I don't know is texting me?

So I have a kik account and someone found me. She starts texting me because apparently her other friends are fake. She asked me how old I was and she said she's eleven. I said to her "I don't know you, I'm NOT telling u how old I'm, don't text me…"
She answered "your mean I just wanted to be your friend."
From my kik profile pic she knows I play minecraft. She asked me to help her on her world and build things. I told her I'll text u pics of how to do a nether reactor then she wanted me to help with animals and farming.
I really don't know what to do.
I don't want to ignore And say get a life and some real friends or help a STRANGER with minecraft worlds.
Yes, I know she could be lying about her age, or playing minecraft, fake friends and her name but you never know
This is really bothering me. I've tried saying just please stop texting me but then she texts something way off subject. She said let's play minecraft together everyday and you can help.
I have no clue where she lives (good for her not telling me) but I didn't ask.
No hate, no unhelpful comments, or spam… Just help
