if(err){
console.log(err);

</div>
<% }); %>
</div>
</div>

console.log the campground

Answer 1

The find method in MongooseJS returns a Query object (reference). There are a few ways you can do searches and return results.
campground.find().exec(function(err,result){
if(err){
console.log(err);
}
else{
res.render("index.ejs",{campground:result});
}
});

Answer 2

I think you are conflicting variable name
var campground=mongoose.model("campground",campgroundSchema); // here is a campground
app.get("/create",function(req,res){
campground.find({},function(err,result /* <-- */){ // the result is also campgrounnd
if(err){
console.log(err);
}
else{
res.render("index.ejs",{campground:result/* <-- */}); // pass result instead campgrounnd
}
})
});
