Unable to install SSL in Apache

My server is Ubuntu and I am running Apache2. I am using apache to point to my web app loaded in tomcat. Below is my 000-default.conf file.

<VirtualHost *:*>
    ProxyPreserveHost On

    # Servers to proxy the connection, or;
    # List of application servers:
    # Usage:
    # ProxyPass / http://[IP Addr.]:[port]/
    # ProxyPassReverse / http://[IP Addr.]:[port]/
    # Example:
    ProxyPass / http://0.0.0.0:8080/
    ProxyPassReverse / http://0.0.0.0:8080/

    ServerName localhost
</VirtualHost>

<VirtualHost *:443>

    SSL Engine On

    # Set the path to SSL certificate
    # Usage: SSLCertificateFile /path/to/cert.pem
    SSLCertificateFile /etc/apache2/ssl/STAR_myglukose_com.crt

    # Servers to proxy the connection, or;
    # List of application servers:
    # Usage:
    # ProxyPass / http://[IP Addr.]:[port]/
    # ProxyPassReverse / http://[IP Addr.]:[port]/
    # Example:
    ProxyPass / http://0.0.0.0:8080/
    ProxyPassReverse / http://0.0.0.0:8080/

    # Or, balance the load:
    # ProxyPass / balancer://balancer_cluster_name

</VirtualHost>

My pointing to Tomcat is fine but the issue is with SSL. After creating the virtual host for 443, I am unable to restart the apache. I am getting an error. It asks me to refer journalct1 -xe. This file is as below.

I tried various ways to settle this up, including writing the SSL Engine as SSLEngine, executing sudo a2enmod ssl, etc but the same error comes in.

How can I solve this issue?

The error message clearly points out the problem:

AH00526: Syntax error on line 19 of /etc/apache2/sites-enabled/000-default.conf:
Invalid command 'SSL', perhaps misspelled or defined by a module not included in the server configuration

To fix the problem look at the specific line:

SSL Engine On

and fix it by removing the space between SSL and Engine: 

SSLEngine On
