Error - ESP8266WiFi.H no such file

Hi, I'm getting the error below and I cannot figure out why! I'm trying to run a servo on pin 9. I have the code below the error as well. Please help. Thanks

Arduino: 1.6.12 (Mac OS X), Board: "Arduino/Genuino Uno"

/Users/harringtonm/Downloads/ServoTest/ServoTest.ino:4:25: fatal error: ESP8266WiFi.h: No such file or directory
#include <ESP8266WiFi.h>

Error compiling for board Arduino/Genuino Uno.

This report would have more information with

option enabled in File -> Preferences.

CODE BELOW

#include <Servo.h>

#define BLYNK_PRINT Serial // Comment this out to disable prints and save space
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
//#include <Servo.h> //see this documentation for library syntax and examples: Servo - Arduino Reference

//char auth[] = "7eaee44698f54dd8a9fc65876bd8d32c"; //Pfost phone
char auth[] = "6c6a2ae8df98407d86a14d5fd1495081"; //Cramer phone
char ssid[] = "FAHotspot";
char pass[] = "AtlantaSymphony123";

void setup (){
Servo myservo;
myservo.attach(15); // the syntax here is myservo.attach(pin); or myservo.attach(pin, min, max); this example has the servo attached to pin 9
myservo.write(90); // set servo to mid-point
Serial.begin(9600);
}
void loop()
{
Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 8442);
Blynk.run();
}

You're trying to compile a program written for an ESP8266 for an Arduino UNO, that won't work.
