At the very least, you should give credit to Harsh VLOGS. Each and every single point you have copied from his video. There is nothing wrong with taking ideas from others' videos, but a little credit would be very just for the hours of hard work the creators put in.
I agree buddy even i don’t mind giving credits to any of my fellow creator but bro every creator makes his/her own script and if sometimes content is same so the facts are also same that’s why it seems to be similar but anyways if you say i agree.
