Our home was severely damaged

At midnight January 9th, my autistic son Alexi, woke up because he heard something.... January 9th is his birthday... He's 20 today... But what he heard was the start of a nightmare. He immediately saw flames from outside his window. He scrambled up .. Calling 911 and ran to our room. My husband and I along with my older son we all completely asleep. Alexi best on our doors screaming and we all ran to see the front wall of my home in flames... Smoke had just broken through. It filled the house..I got my son and our dogs and we ran out of the back... Alexi got the water hose and Mark, my husband, and Lukus , my older son started fighting it ... Exhausting our fire extinguishers... They fought it with the water hose till the fire department arrived. It was so hot the windows shattered... We don't have fire insurance.. We need help.. Please..
