You know some people are making up email to enter the app fastly. I want to check the user mail is real, not fake. I did some seacrhing , is there any other way without email verification? How can I control this situation? Thank you all.

There are some API options you can call to verify the existence of an email address. For example this one offers a Rest API for that.
If you meant inside firebase. Nope, there is no way. In my most recently app you can even create users with emails such as abc@mail.com and it accepts. It only validates for email format, not existence, so if you do something like abc@mail it will through an error.
