        } else {

Answer 1

if you're using mongoose, find method return promise,so make function async and use await before using find :

app.get("/blogs", function async (req, res){
  let blogs = await Blogs.find({});
  res.render("index", {blogs});
});

or
using .then to get data from find method:

app.get("/blogs", function (req, res){
  Blog.find({}).then(blogs=>{
     res.render("index", {blogs}); //if key and value are the same you can skip passing key
  }).catch(err=>{
     console.log(err)
  });
});
